Abstract
A computer system is provided that includes a camera device configured to capture images of a physical scene and a processor configured to store a list of identified blobs. Each identified blob includes a determined blob feature and a path of tracked positions for that identified blob. The processor is configured to receive a series of images of the physical scene from the camera device, detect a candidate blob in a candidate image of the series of images, determine a blob feature of the candidate blob and a position of the candidate blob in the candidate image captured by the camera device. For each identified blob in the list, the processor is configured to compute a match score between the candidate blob and that identified blob.
