Video Analysis

- 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.
