Embodiment Construction
[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] u ^ = arg min u { μ 2 | | u - f | | 2 2 + ...
