Description

technical field

[0001] The invention relates to the field of video image processing, in particular to a reconfigurable parallel image detail enhancement method and device. Background technique

[0002] At present, one of the mainstream development directions of video technology is ultra-high-definition (4K resolution) display technology. Compared with high-definition (1920*1080) video, the number of pixels of 4K video has been increased from 2M to 8M, so higher requirements are placed on the image quality and performance of image enhancement algorithms.

[0003] Traditional video image detail enhancement solutions are mainly designed for high-definition and following standards. When faced with 4K image processing requirements, it is very likely that the processing capacity is insufficient; at the same time, 4K ultra-high-definition images can bring more detailed picture effects , so when the existing detail enhancement algorithm is applied to 4K resolution images, negative ...
