Methods and apparatus for centroid based object segmentation in object recognition-type image processing system

摘要

A digital signal processing system which uses an input image including a plurality of pixels to establish boundaries of objects in the input image. Each of the pixels has a gradient value and the object includes a centroid. Using a segmentation process, the digital signal processing system decides on a perimeter surrounding the object in the input image and then repeatedly searches for a pixel having the highest gradient value and marks that pixel having the highest gradient value as an edge pixel of the object.
