pix_blobtracker

The pix_blobtracker object in Pure Data is a video analysis tool designed to detect and track multiple distinct regions (blobs) within an incoming video stream. It processes the luminance channel of the video, allowing users to configure parameters such as the maximum number of blobs, minimum pixel luminance threshold, and minimum blob size. The object outputs a gemlist containing data about the identified blobs.
