To get useful object detection, I need to remove the contours I do not need. Also find the code on GitHub here. By using our site, you Many of you already asked me for a tutorial on this, So here it is Before I can use the HSV profile values that define the coloured ball, I must convert the captured webcam frame to the HSV colour profile. I can use various image filters to improve the image mask. By using it, one can process images and videos to identify objects, faces, or even the handwriting of a human. Create Mask for object detection or tracking. This will be accomplished using the highly efficient VideoStream class discussed in this tutorial. However, moving webcam or object or even changing light conditions can make the quality of detection unpredictable. Excited by the idea of smart cities? We will use videos from the webcam on our computer for motion detection using OpenCV in Python. However, applying filters to get the perfect mask can be expensive in regards to processing power. Lets begin. As you can see from the example image, with very little Python code, I got good OpenCV object detection. On the other hand, it takes a lot of time and training data for a machine to identify these objects. I opted to detect the plastic ball by colour so I need to set the colour range that I can use to classify each coloured ball. I use an array to hold the values of the lower and upper colour threshold. #!/usr/bin/env python3 """ File: opencv-webcam-object-detection.py This Python 3 code is published in relation to the article below: In this video on OpenCV Python Tutorial For Beginners, I am going to show How to do Object Detection and Object Tracking Using HSV Color Space. ; Use bitwise_and for Object Tracking in OpenCV.
