IMAGE PROCESSING METHOD AND APPARATUS, AND DEVICE AND MEDIUM

The present disclosure relates to an image processing method and apparatus, and a device and a medium. In the present disclosure, after an image subject object in an image to be processed is recognized, and a target polygonal region where part of the image subject object is located inside same and the other part is located outside same is then generated, the image to be processed and an additional image material can be fused according to the target polygonal region to obtain a fused image, such that the image content of the fused image and the image content of the image to be processed are consistent in a first image region including the target polygonal region and an image region occupied by the image subject object, and the additional image material is presented by means of the image content of the fused image in a second image region outside the first image region, and thus the effect of performing stereoscopic display on the image subject object relative to the target polygonal region is presented, thereb
