[0044]The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0045] Such as figure 1 As shown, the present invention proposes a compound regularization image denoising method combined with non-local prior, which includes the following steps:
[0046] 1. Establish an image denoising TV model
[0047] Suppose the image denoising model is:
[0048] f=u+n (3)
[0049] Among them, f is the observed noise image, u is the original real image, and n is the noise.
[0050] The TV model of image denoising is shown in the following formula:
[0051]
[0052] Among them, the first item is the data fidelity item, which requires the noisy image f and the original real image u to be in L 2 In the sense of norm, it is the most similar, that is, the difference is the smallest; the second term is the TV term, which is a priori for the smoothness of image slices to preserve the edge structure characteristics; μ is a regularization...
