No one on you tube do this project for biggener level , but you did in perfect manner Sir Thank you So much Sir.
TNice tutorials is exactly what I needed to understand the UI. Great tutorial!
The best explained video for object detection I've encountered so far!! Keep it up Bro
You explained it very well. You made my day . I am so happy that I had learnt something new.
Thank you very much sir, this was just the perfect introduction t actually implementing computer vision!
Thank you for the expertly presented tutorial and demonstration.
the best video so far and help me a lot. thank you.
This is the most selfless video for object detection have every seen! the steps by steps provided clearly and most important WORKING! it is really helpful for a beginner like me. Thanks author!! You save my life!

Hi it's only detecting person even if it is a car in VideoCapture .it's all good in img detection but the only problem is video object detection. could you please share your code if you've done it

Heyyy..i didn't find frozen_inference_graph.pd after downloading the config file...can you please help!
Simple. And clear tuto thank you so much
Thank you so much for your effort. Really helpful 👍🏽🙏🏼🙌🏽
Amazing tutorial.Thanks Mate
I need to put together a script that copies images containing only certain objects. I tried looking for tutorials, but all of them are hellbent on teaching people how to train AI to tell apart dogs and fish. All I needed was to be spoonfed on how to use a pre-made model. Thank you so much.
Really that details hits different
So informative, thanks a lot!
Amazing video. Great job
Fixed the problem with the bounding boxes: Replace “img” with “frame” in: cv2.rectangle(img,boxes,(255, 0, 0), 2) cv2.putText(img,classLabels[ClassInd-1] ......., thickness=1) Now it should work and display bounding boxes in the video! Great video! Very helpful!

Hi, sir I really appreciate your detailed explanation and it's very easy to understand, there is a mismatch in labels and the pre-trained model. It took me some time but while classifying the images the model predicts the label 'fire hydrant' at position 11 and 'stop sign' at position 13, whereas in the labels list the 'stop sign' comes just after the 'fire hydrant'. How can we solve this problem?
Excellent...!
very informative video and i learnt very much from this , if you could post more tutorials about deep learning and explainations will be helpful.

quick question, what if the frame and classes doesnt show in my video/webcam? is there anything that i can do to fix that?
given it's now 2022, would you suggest a different model that we should use? is this one outdated? or still the same one is good?
awesome
Gud job
Great

Hello Sir, first of all you did a very nice job with easy explanation! Now I found some errors while detecting objects in real-time mode. For instance, phone is detected as a sink, scissors and the chair as a toilet or some kind of staffs. So how can I improve the accuracy of object detection in real time mode? In my case, it is perfectly detecting the person only. Thank you in advance :)

Hi sir, 1) my real time video doesn't capture the whole video. Any ideas on how to get the whole video with detection instead of a screen where the video is only partially visible. 2) the video window doesnt disappear when I stop the jupyter program. I hope you can give us an update. Amazing video!
can you please share the whole code which you just implemented on screen using JN? I will be glad.
Sir in this project how we can add abnormalities part like if two persons are fighting or person is holding nife ,or we can say road accident then how we can show that

Thank you for the great video!! I ran into an issue at the end, the boxes around the objects would not appear on the video, and then the program would crash. The program was definitely counting and labelling the objects, I could see it building a list of everything it detected. Here is the error code: error Traceback (most recent call last) in 13 ret,frame = cap.read() 14 ---> 15 ClassIndex, confidece, bbox = model.detect(frame,confThreshold=0.55) 16 17 print(ClassIndex) error: OpenCV(4.5.1) C:\Users\appveyor\AppData\Local\Temp\1\pip-req-build-kh7iq4w7\opencv\modules\imgproc\src esize.cpp:4051: error: (-215:Assertion failed) !ssize.empty() in function 'cv::resize'
