Abstract
An image processing method and an apparatus (300) are provided, the method includes: obtaining a depth image of a protuberant object (210); selecting a plurality of test points placed on a circle around a pixel in the depth image as a center point of the circle; calculating a protuberance value of the center point based on a comparison between the depth value of the center point and the depth value of each of the selected test points (240); and determining one or more salient points of the protuberant object by using the protuberance value of each pixel in the depth image (250).
