Description
technical field [0001] The present invention relates to the technical field of visual processing, in particular to the visual pre-processing technology based on convolution operation; the reconfigurable visual pre-processor proposed by the present invention can perform real-time visual pre-processing on large-resolution grayscale images. Background technique [0002] Vision is the most important way for human beings to obtain information and knowledge. 80% of the information obtained by humans comes from vision. At the front end of the human visual system, various organizations participate in the pre-processing of visual information, so the human visual system can easily handle visual problems. In order to imitate their own visual function, human beings have carried out a lot of theoretical research and experiments on the visual system. In recent years, vision has not only made great progress in framework models and algorithms, but also has been widely used in advanced man...
