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

An image processing apparatus, comprising:

• at least one memory configured to store program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code comprising:
• attribute characterization obtaining code configured to cause at least one of the at least one processor to obtain an attribute characterization of a source image and an attribute characterization of an enhanced image, the enhanced image being obtained by enhancing the source image;
• attribute characterization comparing code configured to cause at least one of the at least one processor to compare the attribute characterization of the source image with the attribute characterization of the enhanced image to obtain attribute differences between at least part of pixel positions in the source image and corresponding at least part of pixel positions in the enhanced image;
• local fusion weight generating code configured to cause at least one of the at least one processor to determine local fusion weights of the at least part of pixel positions in the source image based on the attribute differences and the attribute characterization of the enhanced image;
• enhanced fusion weight generating code configured to cause at least one of the at least one processor to determine enhanced fusion weights of the at least part of pixel positions in the enhanced image, a determined enhanced fusion weight of at least one pixel position being negatively correlated with a local fusion weight of the same pixel position in the source image;
• and
• fused image generating code configured to cause at least one of the at least one processor to generate a fused image of the source image and the enhanced image.

A non-transitory computer-readable medium storing computer code which, when executed by at least one processor, causes the at least one processor to at least:

• obtain an attribute characterization of a source image and an attribute characterization of an enhanced image, the enhanced image being obtained by enhancing the source image;
• compare the attribute characterization of the source image with the attribute characterization of the enhanced image to obtain attribute differences between at least part of pixel positions in the source image and corresponding at least part of pixel positions in the enhanced image;
• determine local fusion weights of the at least part of pixel positions in the source image based on the attribute differences and the attribute characterization of the enhanced image;
• determine enhanced fusion weights of the at least part of pixel positions in the enhanced image, a determined enhanced fusion weight of at least one pixel position being negatively correlated with a local fusion weight of the same pixel position in the source image;
• and
• fuse the source image and the enhanced image to obtain a fused image.
