Abstract: This disclosure relates to a method for identifying control points, an apparatus and a computer device. Multiple image blocks are obtained by segmenting a target gradient image, and a number of control points to be selected for each image block is determined based on a first preset number of control points and pixel values within each image block. Target control points are therefore identified in the target gradient image based on image block information corresponding to each image block. The target gradient image is a gradient image of a target image of an inspected object. The target image includes any one of a mask image, a live image, or a subtracted image. The image block information includes the number of control points to be selected for the corresponding image block and a size of the image block.
