For the current figures in the literature image restoration technology on the basis of understanding and comprehensive,By reading the image restoration technology related data. this paper focuses on the Wiener (Wiener) filtering, constrained least squares filtering algorithm, Lucy - Richardson algorithm and blind solution convolution algorithm,This paper mainly discusses the Wiener filter, constrained least squares filtering algorithm, Lucy-Richardson algorithm and blind deconvolution algorithm, and its relevant toolbox deconvwnr function, deconvreg function,deconvlucy function, de
