In an image restoration process,the detection of a singularity set will significantly affect the accuracy of the results due to the interference of noise,and it is easy to fall into a local optimum during the iterative detection process.In this paper,an image denoising algorithm for singularity set detection based on a wavelet frame with ran-dom unidirectional variation is proposed based on the idea of random global search and the mutation operation of ge-netic algorithm.The operation time can be greatly shortened,while image recovery effect is maintained.Finally,the effectiveness of the algorithm is verified by experiments.
