Meanshift and Camshift

We have already seen an example of color-based tracking. It is simpler. This time, we see significantly better algorithms like "Meanshift", and its upgraded version, "Camshift" to find and track them.
Optical Flow

Now let's discuss an important concept, "Optical Flow", which is related to videos and has many applications.
Background Subtraction

In several applications, we need to extract foreground for further operations like object tracking. Background Subtraction is a well-known method in those cases.
