DEFOCUS ESTIMATION FROM SINGLE IMAGE BASED ON LAPLACIAN OF GAUSSIAN APPROXIMATION
A defocus estimation algorithm is described herein. The defocus estimation algorithm utilizes a single image. A Laplacian of Gaussian approximation is determined by computing a difference of Gaussian. Defocus blur is able to be estimated by computing a blur difference between two images using the di...
