pix_movement2

The pix_movement2 object is a time-based IIR filter designed for motion detection in video streams. It analyzes the current frame against two previous frames and a user-defined background image, outputting a greyscale image highlighting detected movement. It includes adjustable threshold parameters (lo_threshold, initial_threshold) to filter out image noise and dynamically adapt to changing conditions.
