Abstract

The present disclosure provides an image processing method, including: acquiring an image sequence, the image sequence includes a plurality of images, and each image in the plurality of images includes m×n pixel points, where m is a positive integer , n is a positive integer; for a pixel at a specific position in the m×n pixels, k models are established for the pixel at the specific position according to the previous i images in the image sequence, where i is a positive integer, k is a positive integer; and according to the k models of the pixel points at the specific position, the pixel point at the corresponding position of at least one image in the image sequence is matched, and the corresponding position is determined according to the matching result. Whether the pixel at the position is the moving target pixel.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and more specifically, to an image processing method and an image processing system. Background technique [0002] With the rapid development of computer technology, computer vision technology is increasingly used in many fields such as artificial intelligence, automatic driving, security and daily life. The moving target recognition and tracking technology of image sequence is an important topic in the field of computer vision, and its purpose is to accurately identify the desired moving target from the background environment through computer vision. [0003] In the prior art, the image sequence is usually identified by the method of inter-frame difference, that is, by performing differential processing on two adjacent frames of images, the pixels whose absolute difference is greater than the threshold are considered as the pixels of the moving target . [0004] In the process of re...
