Image coarsening circuit and method for coarsening image

Abstract

The invention discloses an image coarsening circuit and a method for coarsening an image. The image coarsening circuit consists of five parts, such as a read-only memory, a read-write memory, a power supply circuit, an image processing circuit and a communication control circuit, wherein the image processing circuit is respectively connected with the read-only memory, the read-write memory, the communication control circuit and a video input port; a static picture grabbed from a video stream or any picture input by a USB (Universal Serial Bus) port can be realized to be divided into X<2> sub-blocks in an X*X way through the circuit; then the pixel average values of the sub-blocks can be obtained by totaling and summing the pixel values of the sub-blocks; finally the coarsened image of an original image is rearranged by those obtained pixel average values according to the arrangement sequence of the original image, so that the problem that hardware configuration requirements are higher in the existing image coarsening technology can be solved.

Description

technical field [0001] The invention relates to the field of electronic image processing, in particular to an image roughening circuit and a method for roughening an image. Background technique [0002] The image roughening circuit is an electronic device used to simplify the processing of electronic images, reduce the pixel value, and only retain the shape features and basic colors of the original image. In real life, the occasions that require electronic image roughening processing involve Various fields, such as: license plate recognition, fingerprint recognition, etc. [0003] The image processing circuit in traditional technology basically adopts different feature extraction algorithms according to specific application requirements in order to reliably and accurately extract image features and provide good samples for various subsequent occasions; however, due to its The image feature extraction algorithm is specific according to different application cases, so there i...
