Image processing method and apparatus, computer device, and storage medium

An apparatus for determining a target image region of a target object in a target image, the apparatus comprising:

• a memory storing instructions;
• and
• a processor in communication with the memory, wherein, when the processor executes the instructions, the processor is configured to cause the apparatus to perform:
• obtaining a target image comprising a target object,
• obtaining an original mask and an image segmentation model, the image segmentation model comprising a first unit model and a second unit model,
• downsampling the original mask based on a pooling layer in the first unit model to obtain a downsampled mask,
• extracting region convolution feature information of the target image based on a convolution pooling layer in the second unit model and the downsampled mask,
• updating the original mask according to the region convolution feature information, and
• in response to the updated original mask satisfying an error convergence condition, determining a target image region of the target object in the target image according to the updated original mask.

A non-transitory computer-readable storage medium, storing computer-readable instructions, wherein, the computer-readable instructions, when executed by a processor, are configured to cause the processor to perform:

• obtaining a target image comprising a target object;
• obtaining an original mask and an image segmentation model, the image segmentation model comprising a first unit model and a second unit model;
• downsampling the original mask based on a pooling layer in the first unit model to obtain a downsampled mask;
• extracting region convolution feature information of the target image based on a convolution pooling layer in the second unit model and the downsampled mask;
• updating the original mask according to the region convolution feature information;
• and
• in response to the updated original mask satisfying an error convergence condition, determining a target image region of the target object in the target image according to the updated original mask.
