Embodiment Construction
[0018] see figure 1 , figure 1 It is a flowchart of the present invention, and its specific implementation steps are as follows:
[0019] 1. Perform two-dimensional wavelet transform on the defect image:
[0020] The three color channels of the color image to be repaired are respectively subjected to wavelet transformation, and each channel is decomposed into a low-frequency sub-image and three high-frequency sub-images (including horizontal high-frequency, vertical high-frequency and diagonal high-frequency sub-images), and the decomposition The subsequent sub-images at all levels contain the spatial structure information of the original image. According to the Mallat algorithm, the specific process of two-dimensional wavelet transform is as follows:
[0021] A ( i , j ) = Σ m , n l ...
