Abstract

The invention provides an image segmentation method and device, electronic equipment and a storage medium. The method comprises the following steps: carrying out down-sampling coding on a to-be-segmented image comprising a foreground and a background, and carrying out up-sampling decoding on an obtained down-sampling feature map to obtain an up-sampling feature map; carrying out classification processing on the up-sampling feature map to obtain classification probabilities of foregrounds and backgrounds corresponding to all pixels in the up-sampling feature map; performing compensation processing on errors of classification probabilities of foregrounds and backgrounds corresponding to the pixels to obtain a compensation feature map of the up-sampling feature map; performing fusion processing on the compensation feature map, the up-sampling feature map and the down-sampling feature map to obtain a fusion feature map; and identifying the foreground and the background from the to-be-segmented image based on the classification probability of the foreground and the background corresponding to each pixel in the fusion feature map. According to the invention, image segmentation can be accurately carried out.

Description

technical field [0001] The invention relates to an image processing technology based on artificial intelligence, in particular to an image segmentation method, an image background replacement method, a device, electronic equipment and a storage medium. Background technique [0002] Artificial Intelligence (AI) is a comprehensive technology of computer science. By studying the design principles and implementation methods of various intelligent machines, the machines have the functions of perception, reasoning and decision-making. Artificial intelligence technology is a comprehensive subject that involves a wide range of fields, such as natural language processing technology and machine learning / deep learning. With the development of technology, artificial intelligence technology will be applied in more fields and play an increasingly important role. increasingly important value. [0003] In the image processing technology based on artificial intelligence, image segmentation ...
