[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] In image restoration, the image degradation model can be expressed by the following formula:
[0023] f ( x , y ) = k ( x , y ) ⊗ g ( x , y ) + n ( x , y )
[0024] Among them, g(x,y) is the original image, It is a convolution operation, k(x,y) represents the blur kernel that blurs the image, also called the point spread function, n(x,y) is additive noise, and f(x,y) is a known degraded image.
[0025] A video sequence is composed of several frames of images, and each frame can be re...
