Track objects with Camshift using OpenCV
OpenCV is the huge open-source library for computer vision, machine learning, and image processing and now it plays a major role in real-time operation which is very important in today’s systems. By using it, one can process images and videos to identify objects, faces, or even the handwriting of a human.
Camshift or we can say Continuously Adaptive Meanshift is an enhanced version of the meanshift algorithm which provides more accuracy and robustness to the model. With the help of Camshift algorithm, the size of the window keeps updating when the tracking window tries to converge. The tracking is done by using the color information of the object. Also, it provides the best fitting tracking window for object tracking. It applies meanshift first and then updates the size of the window as:
It then calculates the best fitting ellipse to it and again applies the meanshift with the newly scaled search window and the previous window. This process is continued until the required accuracy is met.
Note: For more information about meanshift refer to Python OpenCV: Meanshift
Below is the implementation.
