Uncontrolled operation method for non linear and non local filter, involves computing linear regression for two measurable characteristics with polynomial, which approximates values of reference pixel

摘要

The method involves extracting good images on the basis of topological median filter by X-ray and selecting central pixels (c) with correlated reference pixels (R). Computation of the linear regression for two measurable characteristics with a polynomial approximates the values at the position of the reference pixel after the line profile of the central pixel. The search area on area of special interest is restricted. The search strategy is selected, such that all information is figured first, which is computed through non-recurring access on all pixels of the good images. Each pixel is assigned to a similar class performance and the search of the reference pixels for all central pixels takes place under consideration of their class.
