Embodiment Construction
[0071] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention should not be limited thereby.
[0072] This embodiment adopts the color image of Tree whose size is 256x256, see figure 1 , denoted as X∈R n×n , where n=256.
[0073] A color digital image restoration method based on compressed sensing, comprising the steps of:
[0074] The first step is to preprocess the original damaged image. In this embodiment, the image processing tool Adobe Photoshop is used to assign the R, G, and B values of the image damage to 0, that is, the damaged part of the image is processed as black, so that the subsequent Steps are processed, and the color image is obtained after processing in this step, such as figure 2 shown.
[0075] In the second step, the image is divided into blocks to obtain multiple image blocks, and then each image block is analyzed to generate a degra...
