Patent ID: 8300937

Claim:
An image segmentation method based on region features of pixels, comprising: when an input image is retrieved, sequentially scanning pixels of the input image row by row; determining signs of unmarked pixels of the input image according to region features of neighboring pixels for each of the pixels of the input image; updating a region-sign feature table according to pixel signs of the input image; recording the updated pixel signs to generate a region-sign update table; sequentially scanning the pixels of the input image row by row; and updating region signs of related pixels according to the region-sign update table; wherein determining the signs of unmarked pixels further comprises: extracting features of an unmarked pixel and features of region signs corresponding to neighboring pixels for the unmarked pixel when the unmarked pixel is obtained; comparing the features of the unmarked pixel with the features of region signs corresponding to the neighboring pixels to determine a sign of the unmarked pixel; updating features of corresponding region signs according to the determined sign of the unmarked pixel; recording the updated region signs; and updating the region-sign feature table and the region-sign update table so that the unmarked pixel becomes a marked pixel.
