No one on you tube do this project for biggener level , but you did in perfect manner Sir Thank you So much Sir.

[@madarbakushussain758]

The best explained video for object detection I've encountered so far!! Keep it up Bro

[@weixinteh7075]

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!

[@TOI700e13]

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

[@BruceWayne-xq7bb]

bro, can u give the graph of deep learning architecture? u did not provide that link

[@sudeep003gowda]

You explained it very well. You made my day . I am so happy that I had learnt something new.

Thank you for the expertly presented tutorial and demonstration.

[@Radi0he4d1]

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.

[@Raini41]

the best video so far and help me a lot. thank you.

[@sangeetagarg239]

great job, Could you please teach me how a new dataset is labelled and implementation of all the approaches of object detection. As I am new to this area. I liked the way you described.

[@karthikeyaanar]

Thank you so much for your effort. Really helpful 👍🏽🙏🏼🙌🏽

[@SteelersFans99]

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!

Simple. And clear tuto thank you so much

[@pranavgupta9015]

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?

[@prarthana_bhuyan]

Thanks for teaching such complicated concept in simple words. Kindly guide me if we can integrate hardware like LED etc to such projects after detecting a specific object in real time.

[@albertbenedict]

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?
