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

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

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.

@SteelersFans99 3 года назад

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!

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.

@pranavgupta9015 3 года назад

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?

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 :)
