Embodiment Construction
[0041] The image noise reduction method based on K-SVD and local linear nesting of the present invention will be further elaborated below in conjunction with the accompanying drawings.
[0042] Such as figure 1 , figure 2 As shown, an image denoising system based on K-SVD and local linear nesting includes the following modules: sampling module, calculating Laplacian matrix L module, objective function construction and dictionary, sparse coefficient optimization module, and estimating image block An acquisition module, an overall estimation image block acquisition module;
[0043] Noisy image→sampling module→calculate Laplacian matrix L module→objective function construction and dictionary, sparse coefficient optimization module→estimation image block acquisition module→overall estimated image block acquisition module→denoising image;
[0044] Described objective function construction and dictionary, sparse coefficient optimization module comprise overall objective function ...
