[0032] The saliency map-based variable block image restoration method of the present invention will be described in detail below with reference to the accompanying drawings and examples.
[0033] refer to figure 1 , the variable block image inpainting method based on the saliency map includes the following steps:
[0034] 1), Input the image to be repaired to generate a known area saliency map, such as figure 2 (a) shows the original image before restoration, Ω represents the unknown area, and Φ represents the known area.
[0035] (11), feature extraction: first represent the image to be repaired as a 9-layer Gaussian pyramid. The 0th layer is the input image, and the 1st to 8th layers are the images formed by filtering and sampling the input image with a 5*5 Gaussian filter respectively, and the sizes are 1 / 2 to 1 / 256 of the input image respectively. Then extract various features for each layer of the pyramid: brightness I, red R, green G, blue B, yellow Y and direction O...
