Optical Flow Operations

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.

Compute Optical Flow

compute_optical_flow(image1, image2[, ...])

Compute the optical flow between two images using the DIS method of OpenCV.

Display Optical Flow

display_optical_flow(image, flow_x, flow_y)	Display the optical flow overlaid on the given image using Matplotlib.
display_optical_flow_quiver(image1, image2, ...)	Display the optical flow as a quiver plot overlaid on the given images using Matplotlib.
