WebS.S. Al-Amri [2] introduce blur is unsharp image area caused by camera or subject movement, inaccurate focusing, or the use of an aperture that gives shallow depth of field. He introduced three types of blurring: Average blur, Gaussian blur, and motion blur. Y. Yitzhaky [10] introduces motion blur phenomena. WebUse la desconvolución para enfocar imágenes borrosas Un tipo de distorsión común en las imágenes es el efecto de desenfoque, que puede deberse al movimiento o a una lente mal enfocada. El efecto de desenfoque se representa mediante un operador de distorsión, que también se conoce como función de dispersión puntual (PSF).
