Abstract:
1. A method of evaluating the quality of an image comprising at least one zone, wherein the method comprises the steps of: determining at least one of a parameter associated with at least one zone and a parameter associated with a distribution pattern of sampling points within the at least one zone, wherein the at least one parameter is determined based on at least one of the following: delineating the at least one zone in the image, disposing the sampling points within the at least one zone, identifying data that indicates a position and an optical characteristic value of each of the sampling points within the at least one zone which are determined based at least on the at least one parameter; performing Fourier analysis on the data relevant to the at least one zone to obtain an image quality of the at least one zone; and determining the quality of the image based on the image quality of the at least one zone.
