DEPTH/DISPARITY MAP POST-PROCESSING METHOD AND DEVICE

摘要

A depth/disparity map post-processing method and device adopting a strategy of combining edge information and segmentation information when detecting irregular edge regions. The method comprises: dividing a color image into super-pixels when performing image segmentation on the color image; partitioning a grayscale range into a preset number of intervals, and analyzing each of the super-pixels statistically to obtain a histogram of all the pixel points falling between the intervals; determining, in a current super-pixel, whether a ratio of the number of pixels contained in the interval having a maximum interval distribution value, to the total number of pixels in the current super-pixel is less than a first threshold, and if so, further dividing the current super-pixel by adopting a color-based segmentation method. The present invention improves the accuracy of color image division while ensuring an image processing speed, thus improving the accuracy of irregular edge region detection.
