1 00:00:02,540 --> 00:00:06,770 The last tutorial we have seen that how we can integrate your V9 with flask. 2 00:00:06,770 --> 00:00:10,970 So now we will just go ahead and complete this complete web app. 3 00:00:11,210 --> 00:00:18,320 So before we go ahead, uh, in towards the HTML and CSS code, we need to, uh, complete this flask 4 00:00:18,320 --> 00:00:19,910 app.py file as well. 5 00:00:22,790 --> 00:00:29,000 So we will just, uh, import a few other libraries and we will, uh, create a flask form so that user 6 00:00:29,000 --> 00:00:32,300 can upload a file, whether it's image or a video file. 7 00:00:32,300 --> 00:00:34,040 So let's get started with it. 8 00:00:34,040 --> 00:00:36,470 And we need to install some packages as well. 9 00:00:41,310 --> 00:00:45,150 So I will just write from last the WDF. 10 00:00:47,020 --> 00:00:49,750 Or knobs on. 11 00:00:50,740 --> 00:00:51,400 Okay. 12 00:00:53,500 --> 00:00:58,780 So next I will just write WP forms. 13 00:01:01,380 --> 00:01:01,830 All. 14 00:01:12,860 --> 00:01:13,430 Doublet. 15 00:01:14,090 --> 00:01:14,450 The. 16 00:01:20,050 --> 00:01:23,230 And I will just report this as well. 17 00:01:40,730 --> 00:01:44,210 And we will just try to port from the forms. 18 00:01:45,330 --> 00:01:46,680 Dot validators. 19 00:01:46,710 --> 00:01:53,400 So, uh, to just make sure that the user uploads a video file and the user, uh, the file that the 20 00:01:53,400 --> 00:01:58,020 video file or image file that the user has uploaded is in the correct format. 21 00:02:01,760 --> 00:02:04,760 So this is the need for the validators. 22 00:02:07,040 --> 00:02:07,520 Okay. 23 00:02:07,520 --> 00:02:23,270 So now we'll just install this pip install uh wp forms loss wp f for I, uh, I desktop and I will just 24 00:02:23,270 --> 00:02:28,550 open uh, the requirements.txt file as well. 25 00:02:29,510 --> 00:02:31,880 Let me add all these packages over here. 26 00:02:41,940 --> 00:02:42,960 And. 27 00:02:42,960 --> 00:02:43,320 Okay. 28 00:02:43,320 --> 00:02:44,010 So. 29 00:02:46,170 --> 00:02:47,250 That looks lost. 30 00:02:47,550 --> 00:02:48,540 WTF? 31 00:02:52,790 --> 00:02:55,340 Well, I think these are quite packages. 32 00:02:55,370 --> 00:02:56,420 You have all this? 33 00:02:59,210 --> 00:03:06,080 So now we will use the task form to get the input file. 34 00:03:08,440 --> 00:03:10,600 But all the agents that. 35 00:03:13,120 --> 00:03:14,410 Oversight got lost. 36 00:03:14,410 --> 00:03:15,100 Upload. 37 00:03:17,370 --> 00:03:18,450 Rainfall. 38 00:03:38,370 --> 00:03:39,150 This type file. 39 00:03:40,050 --> 00:03:40,410 Okay. 40 00:03:40,410 --> 00:03:41,850 We have imported this library. 41 00:03:41,850 --> 00:03:43,140 I can see over here. 42 00:03:45,450 --> 00:03:48,510 And here we have the file that the user will upload. 43 00:03:51,830 --> 00:03:58,370 So the validators make sure that the user upload a file and the file is in the correct format, whether 44 00:03:58,370 --> 00:04:00,230 it's an image file or a video file. 45 00:04:03,590 --> 00:04:06,170 Input required, like validation validators. 46 00:04:06,170 --> 00:04:12,920 Make sure that before the processing begins that the user has uploaded an image or video file. 47 00:04:15,950 --> 00:04:17,540 Then we will have a subnet. 48 00:04:24,130 --> 00:04:28,150 So the user can upload up, uh, submit the input video or image file. 49 00:04:32,210 --> 00:04:32,690 Okay. 50 00:04:32,690 --> 00:04:38,810 And now you can see that in the detection.py file we are just getting the frame rate, the size of the 51 00:04:38,810 --> 00:04:40,820 current frame and total number of detections. 52 00:04:41,660 --> 00:04:41,870 Okay. 53 00:04:41,870 --> 00:04:45,050 So let's complete this up all over here as well. 54 00:05:29,220 --> 00:05:33,930 Paul will keep account of, uh, frame rate or frame per second as well. 55 00:05:33,930 --> 00:05:38,370 So for this we will just write over here is count. 56 00:05:38,370 --> 00:05:43,890 So we are just declaring it with lower bound so that the value can be accessed outside the function 57 00:05:44,130 --> 00:05:45,390 as well. 58 00:05:51,140 --> 00:05:53,780 So this is equal to string. 59 00:05:53,780 --> 00:05:58,580 And this would give us the frame rate will give us the count. 60 00:06:01,070 --> 00:06:01,820 And. 61 00:06:05,300 --> 00:06:08,060 Then we'll also have the frame size. 62 00:06:08,060 --> 00:06:12,770 And to assess this outside the desired frame size zero. 63 00:06:26,720 --> 00:06:30,770 And here we will dictate frame size. 64 00:06:30,950 --> 00:06:34,550 Here I will just take the first index here. 65 00:06:36,710 --> 00:06:38,180 Here we have paint shape. 66 00:06:40,940 --> 00:06:45,620 And now we will also, uh, keep the count of the total number of detected objects. 67 00:06:45,620 --> 00:06:52,880 So just detected objects, and we will just initialize detected objects. 68 00:06:52,880 --> 00:06:53,810 So here. 69 00:07:17,980 --> 00:07:18,550 Okay. 70 00:07:18,550 --> 00:07:19,420 And. 71 00:07:20,640 --> 00:07:23,640 Yeah, we would have protection. 72 00:07:35,290 --> 00:07:35,560 Okay. 73 00:07:38,950 --> 00:07:39,280 Okay. 74 00:07:39,280 --> 00:07:40,930 That's completely fine now. 75 00:07:45,620 --> 00:07:46,550 So blast! 76 00:07:46,550 --> 00:07:50,210 I'll change this URL reflections over here as well. 77 00:07:51,130 --> 00:07:54,130 And we will just create another thing. 78 00:07:54,130 --> 00:07:57,790 Airport road it. 79 00:07:58,390 --> 00:08:00,160 And over here. 80 00:08:01,180 --> 00:08:03,730 Why is it still the front page? 81 00:08:19,940 --> 00:08:22,340 All this will be the front page of our application. 82 00:08:27,080 --> 00:08:30,260 But first we will create an instance for this upload file form. 83 00:08:33,410 --> 00:08:38,750 So I'm just creating an instance of instance of this upload file form over here. 84 00:09:00,220 --> 00:09:06,490 But, uh, when the user uploads an image file or a video file, we'll try to get the file name from 85 00:09:06,490 --> 00:09:06,970 there. 86 00:09:09,070 --> 00:09:12,520 So first we'll just write your name. 87 00:09:17,360 --> 00:09:21,170 Well, I was awarded this library as well, so that's good. 88 00:09:24,490 --> 00:09:27,100 And it will try to get the file path. 89 00:09:41,000 --> 00:09:48,650 And after getting the file path will save that input file into this static files folder. 90 00:09:48,650 --> 00:09:50,900 So over here the input file will be saved. 91 00:10:15,650 --> 00:10:19,160 So we will just create a session storage over here as well. 92 00:10:26,030 --> 00:10:27,950 I will save the file path. 93 00:10:29,270 --> 00:10:29,750 Okay. 94 00:10:34,050 --> 00:10:34,230 He. 95 00:10:37,520 --> 00:10:45,290 So if the user uploads an input file and we have made sure that the user uploaded the file and it's 96 00:10:45,290 --> 00:10:50,300 in the correct format, then we will save the file into the static file folder. 97 00:10:50,300 --> 00:10:55,400 And in the session storage we will have the video path of the file. 98 00:10:55,400 --> 00:10:57,860 And then we will just render the template. 99 00:11:03,110 --> 00:11:04,850 I will just add a flash HTML file. 100 00:11:04,850 --> 00:11:07,190 I've already done the HTML css code. 101 00:11:11,750 --> 00:11:16,760 We have a great instance of the upload file form over here, so that's no worries. 102 00:11:18,680 --> 00:11:23,540 So if we are here that means that uploaded store the user has uploaded a file. 103 00:11:26,870 --> 00:11:28,760 And for file name we have. 104 00:11:32,760 --> 00:11:35,190 House band with the standard template. 105 00:11:39,700 --> 00:11:40,690 Swong. 106 00:11:40,690 --> 00:11:41,710 Uploaded. 107 00:11:43,930 --> 00:11:46,300 All rounds and the final. 108 00:11:50,540 --> 00:11:52,550 Okay, so that's completely great. 109 00:11:52,580 --> 00:11:55,550 Uh, we are just, uh, on our land from here. 110 00:11:56,450 --> 00:11:57,680 Okay, so. 111 00:12:00,680 --> 00:12:01,430 Well, okay. 112 00:12:04,220 --> 00:12:08,210 So now I will just add up all my HTML, CSS code. 113 00:12:11,910 --> 00:12:18,150 I will just go over here and create a new directory over here by the name templates. 114 00:12:19,680 --> 00:12:22,980 And inside this I will add my HTML file. 115 00:12:42,260 --> 00:12:44,660 But let me add that HTML file over here. 116 00:12:48,450 --> 00:12:51,210 Well, I went and restored each HTML file over here. 117 00:12:51,210 --> 00:12:59,070 Like, you can see all the HTML code over here and here in the static I have this CSS file Python file. 118 00:12:59,070 --> 00:12:59,430 Okay. 119 00:12:59,430 --> 00:13:02,760 And here is the logo which will be appearing in the web app. 120 00:13:02,760 --> 00:13:04,590 And this is the tablet image. 121 00:13:04,590 --> 00:13:11,070 Inside this I will just display my output image or video with the different objects being detected inside, 122 00:13:11,070 --> 00:13:11,940 uh, over them. 123 00:13:12,330 --> 00:13:12,870 Okay. 124 00:13:13,260 --> 00:13:18,180 So that's all, um, you can just keep this as HTML code. 125 00:13:18,180 --> 00:13:21,780 There is nothing, uh, very special about this HTML code. 126 00:13:21,780 --> 00:13:24,510 Uh, this is very simple HTML code. 127 00:13:24,990 --> 00:13:25,410 Okay. 128 00:13:25,410 --> 00:13:28,830 So let's run this up and see how this works. 129 00:13:36,040 --> 00:13:37,000 Yes, or. 130 00:13:42,010 --> 00:13:47,590 Uh, instead of this, uh, how we would have created this HTML, uh, file. 131 00:13:47,590 --> 00:13:50,770 So let me just show you an overview of this. 132 00:13:52,880 --> 00:13:55,520 And also there's not a very correct. 133 00:13:55,520 --> 00:14:04,940 I just make my songs last like let's first execute it and then I will explain you the SQL code as well. 134 00:14:09,090 --> 00:14:11,940 But before we run this, we need to complete our. 135 00:14:11,940 --> 00:14:13,290 We need to make few changes. 136 00:14:15,000 --> 00:14:16,470 We just forgot this. 137 00:14:16,500 --> 00:14:20,280 We need to add video path over here as well. 138 00:14:21,300 --> 00:14:25,770 And yeah, we'll try to get, uh, the video back from the session. 139 00:14:25,770 --> 00:14:26,460 Storage. 140 00:14:28,720 --> 00:14:33,430 Okay, so inside this session storage I have just saved my video path. 141 00:14:33,850 --> 00:14:34,240 Okay. 142 00:14:34,240 --> 00:14:36,190 So I will try to get it over here. 143 00:14:45,290 --> 00:14:47,750 So you are able to get the video part. 144 00:14:54,340 --> 00:14:59,200 And I would just say radio Bob and Alex. 145 00:15:01,290 --> 00:15:01,860 They're gone. 146 00:15:07,530 --> 00:15:09,810 Okay, so that's completely fine now. 147 00:15:17,290 --> 00:15:17,560 Okay. 148 00:15:17,560 --> 00:15:20,110 So let's see how does it works. 149 00:15:20,110 --> 00:15:24,460 Whether we are applet upload or able to upload an image file or video file. 150 00:15:24,790 --> 00:15:34,360 Well, instead of video path or record if it is right file path because we can upload an image or video. 151 00:15:42,370 --> 00:15:42,970 O-kin. 152 00:15:43,510 --> 00:15:46,150 Well, now it's it looks more. 153 00:15:47,440 --> 00:15:52,060 Okay, so so let's see how does it goes. 154 00:15:53,140 --> 00:15:54,040 Okay. 155 00:15:55,420 --> 00:15:58,780 And expression is not defined. 156 00:16:08,610 --> 00:16:10,680 Import this driver over here. 157 00:16:10,680 --> 00:16:10,890 And. 158 00:16:13,970 --> 00:16:14,120 Well. 159 00:16:14,120 --> 00:16:14,510 God's. 160 00:16:16,380 --> 00:16:17,850 Refresh the support here. 161 00:16:21,330 --> 00:16:23,940 And hopefully this issue will be fixed now. 162 00:16:34,740 --> 00:16:41,850 If so, let me upload an image file and if I just click on the play okay. 163 00:16:43,140 --> 00:16:44,640 We have an error. 164 00:16:47,800 --> 00:16:53,500 Edwards there in such joint spelling mistake. 165 00:16:56,590 --> 00:16:57,340 So let's see. 166 00:16:57,370 --> 00:16:57,940 Or does it. 167 00:16:57,940 --> 00:16:58,810 Cause now. 168 00:17:15,120 --> 00:17:17,520 Okay, so let me upload an image file over here. 169 00:17:23,830 --> 00:17:29,560 Um, I'm just, uh, trying to see the terminal with all the press. 170 00:17:31,750 --> 00:17:31,990 We. 171 00:17:31,990 --> 00:17:34,120 I hope we will be able to see some results now. 172 00:17:36,270 --> 00:17:38,040 Okay, so now you can say it's working. 173 00:17:38,040 --> 00:17:41,220 We are able to take this person's traffic lights over here. 174 00:17:41,640 --> 00:17:41,970 Okay. 175 00:17:41,970 --> 00:17:42,660 So that's good. 176 00:17:44,160 --> 00:17:44,490 Okay. 177 00:17:44,490 --> 00:17:46,230 So let's upload this video. 178 00:17:46,260 --> 00:17:47,010 Let's see. 179 00:17:47,070 --> 00:17:51,090 So all these icons are different world like all these icons. 180 00:17:51,090 --> 00:17:56,040 Uh, we can use these icons later on for different, uh, for different functions. 181 00:17:56,040 --> 00:17:58,530 But currently the first two icons are working well. 182 00:17:58,710 --> 00:18:00,450 This is the upload button icon. 183 00:18:00,450 --> 00:18:04,830 And this is the play button icon so that you can do object detection on image or video. 184 00:18:04,830 --> 00:18:06,780 From here you will upload an image file. 185 00:18:07,170 --> 00:18:11,490 So now you can see over here we are able to track different person handbag over here. 186 00:18:11,490 --> 00:18:16,530 In the same way you can uh do object detection on some other image or video as well. 187 00:18:17,190 --> 00:18:19,170 So previously you have tested on a video. 188 00:18:22,780 --> 00:18:23,050 Now. 189 00:18:28,330 --> 00:18:28,630 Okay. 190 00:18:28,630 --> 00:18:33,370 In the same way you can, uh, like you can see over here we have detected four different persons and 191 00:18:33,370 --> 00:18:35,230 one football in the same way. 192 00:18:35,320 --> 00:18:38,380 You can upload some other video over here as well. 193 00:18:47,460 --> 00:18:48,780 Like you can see over here. 194 00:18:48,780 --> 00:18:51,150 We are able to detect different cars over here. 195 00:18:51,150 --> 00:18:55,440 I'm testing on CPU, so the processing is very slow currently. 196 00:18:58,800 --> 00:18:59,370 Okay. 197 00:18:59,790 --> 00:19:03,540 So like you can see that there. 198 00:19:03,540 --> 00:19:05,550 The cars are moving over here. 199 00:19:06,150 --> 00:19:06,720 Okay. 200 00:19:06,720 --> 00:19:07,350 So. 201 00:19:11,390 --> 00:19:18,500 Less of one thing we can do is like, you can see that, uh, we are just getting the FPS count, frame 202 00:19:18,500 --> 00:19:20,030 size, total detected object. 203 00:19:23,830 --> 00:19:26,260 We cannot go right over here. 204 00:19:26,260 --> 00:19:27,580 App dot route. 205 00:19:30,800 --> 00:19:31,460 First. 206 00:19:33,500 --> 00:19:34,490 Methodist. 207 00:19:43,580 --> 00:19:48,350 We are just creating a URL by the name so that we can get the frame rate. 208 00:19:50,540 --> 00:19:54,740 Or know that we have created a global yes count. 209 00:19:55,130 --> 00:19:58,880 And inside this variable we have the our frame rate stored. 210 00:20:01,390 --> 00:20:01,720 Or. 211 00:20:03,370 --> 00:20:05,890 We need to import the library. 212 00:20:14,490 --> 00:20:17,820 And just go hard for this, I think as well. 213 00:20:41,940 --> 00:20:44,370 And now we have a plot for. 214 00:20:51,820 --> 00:20:54,730 Well, in the deacon we have the total number of detections out. 215 00:21:36,970 --> 00:21:38,860 And then we can also get the. 216 00:21:41,020 --> 00:21:42,580 Frame size as well. 217 00:22:23,860 --> 00:22:26,680 Okay, so we are done with all this up now. 218 00:22:29,210 --> 00:22:30,770 Lesson.i, you can say. 219 00:22:32,990 --> 00:22:36,560 We have made some changes in the code and debugging for the new changes. 220 00:23:16,490 --> 00:23:21,470 But now you can see that, um, the object detection is being downloaded this video and let's see if 221 00:23:21,470 --> 00:23:22,880 we are able to get the frame rate. 222 00:23:22,880 --> 00:23:26,150 So now you can see that the frame rate is 0.172. 223 00:23:26,390 --> 00:23:30,020 And let's see what is the total number detection score. 224 00:23:30,020 --> 00:23:36,140 So in this current frame we have six total detections count like six different jets are detected. 225 00:23:36,140 --> 00:23:38,210 And let's see what is the frame size. 226 00:23:38,210 --> 00:23:40,880 So the frame size is 1020 okay. 227 00:23:40,880 --> 00:23:42,650 So we can upload an image file. 228 00:23:42,650 --> 00:23:44,960 And let's see how does it work. 229 00:23:44,960 --> 00:23:45,680 So. 230 00:23:53,930 --> 00:23:59,210 So let's say in this case total number of detections. 231 00:23:59,210 --> 00:24:00,800 Now 22. 232 00:24:00,830 --> 00:24:01,880 Let's count this. 233 00:24:02,180 --> 00:24:08,090 So 123456789 234 00:24:08,090 --> 00:24:16,400 1011 1213 1415 1617 1821 1920 2122. 235 00:24:16,400 --> 00:24:17,720 So yes, there are 22. 236 00:24:17,930 --> 00:24:20,420 And what is the frame size? 237 00:24:20,870 --> 00:24:21,080 Okay. 238 00:24:21,080 --> 00:24:23,750 664 and that's correct okay. 239 00:24:23,750 --> 00:24:25,640 So that's all from this tutorial. 240 00:24:25,640 --> 00:24:29,720 In this tutorial we have learned how we can create a complete web app using flask. 241 00:24:29,720 --> 00:24:32,000 And you can see that we have test. 242 00:24:32,090 --> 00:24:35,150 We have done object detection on images videos. 243 00:24:35,150 --> 00:24:38,180 And we have also tested on the live webcam feed as well. 244 00:24:38,180 --> 00:24:39,680 So that's all from this tutorial. 245 00:24:39,680 --> 00:24:40,760 Thank you for watching.
