SYSTEM AND METHOD FOR ADAPTIVE PIXEL SEGMENTATION FROM IMAGE SEQUENCES

摘要

The image processing system includes an image processor performing adaptive pixel segmentation for a sequence of image frames collected during movement relative to a scene, with each image frame having a plurality of pixels. An image sensor collects the sequence of image frames while moving relative to the scene. The image processor may perform the adaptive pixel segmentation by generating a probability density function (PDF) for pixels based upon a plurality of past image frames from the sequence thereof, determining whether pixels in a new image frame from the sequence thereof are independently moving pixels or background pixels based upon comparing the new image frame to the at least one PDF, and updating the at least one PDF based upon the new image frame.
