The package includes functions to compute the optical flow between two images based on ``OpenCV`` ``DIS`` (Dense Inverse Search) algorithm. The optical flow can be computed for a specific channel of the images and for a specific region of interest. 
The computed optical flow can be visualized using quiver plots or color-coded flow maps.
