Abstract

The invention discloses an image shadow removal method and a processing terminal. The method comprises the following steps: converting RGB into YUV, obtaining the width and height of an image, constructing an original pixel matrix according to pixel values, and converting the original pixel matrix into a grayscale image; gradually moving by using the first matrix to cover all pixel points in the original pixel matrix, and replacing all the pixel points covered by the current first matrix with a pixel at the center of the matrix every time the first matrix is moved, so as to obtain a first updated pixel matrix; gradually moving a second matrix in the first updated pixel matrix, and replacing all pixel points covered by the current second matrix with a pixel at the center to obtain a second pixel matrix; carrying out normalization processing on the second pixel matrix so as to enable all pixels to be within an allowable range, and obtaining a final pixel matrix; and copying the YUV data, filling the corresponding position of the final pixel matrix with the YUV data, and combining the YUV data with the final pixel matrix to obtain a target image. According to the method, the problem of picture shadow can be well solved, and the image is restored to the greatest extent.

Description

technical field [0001] The present invention relates to the technical field of image shadow processing, in particular to an image shadow removal method and a processing terminal. Background technique [0002] In daily life and work, it is often encountered that there are shadows in the image. These shadows will affect the information that the image itself needs to express, and then affect people's perception. Therefore, it is necessary to remove the shadows in the image. Wherein, the images include frame images in photos, pictures and videos. In existing image shadow removal methods, often only low-resolution images can be processed, and the shadow effect of high-resolution image removal is often not ideal, or manual editing is performed using image processing software (such as Photoshop). Therefore, there is also a need for sophisticated shadow removal methods that can handle high-resolution images. Contents of the invention [0003] For the deficiencies in the prior ar...
