Texture image completion method and device

Abstract

The invention provides a texture image completion method and device. The method comprises steps that a to-be-filled area on a gray texture image is determined, and a filling center point on the to-be-filled area is selected; a to-be-filled block is determined on the basis of image texture characteristics within a preset texture detection scope surrounding the the filling center point; multiple candidate filling blocks are selected from the texture image on the basis of the size of the to-be-filled block, similarities of the multiple candidate filling blocks and the to-be-filled block can be acquired through calculation on the basis of an average pixel gray of the to-be-filled block, and one candidate filling block having highest similarity with the to-be-filled block is selected as an optimal filling block; the optimal filling block is utilized to carry out image filling for the to-be-filled block. The method is advantaged in that the filling block with proper precision can be adaptively selected according to the texture characteristics of the image, more-complex and more-changeable texture images can be processed, the images after completion have better data accuracy and reliability, and calculation efficiency is higher.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a texture image complementing method and device. Background technique [0002] Texture image completion is a technique for image completion of the exact part of the image according to the data characteristics in the texture image. In the existing methods for texture image completion, the accuracy of image completion cannot be selected according to the changing trend of the image. Changed texture image. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a texture image complement method, the method comprising: [0004] Determine the area to be filled on the grayscale texture image, and select a filling center point on the area to be filled; [0005] determining a block to be filled based on image texture features within a preset texture detection range around the f...
