A Recursive Algorithm for Digital Image Processing Using Local Statistics

Abstract

Recently, Jong-Sen Lee proposed an algorithm for contrast enhancement and white noise filtering of a digital image based on local statistics. Lee's algorithm is nonrecursive and requires large computational effort in the calculation of local means and variances for individual pixels. This report presents an algorithm for digital image processing based on local statistics. The algorithm constitutes a recursive implementation of the approach proposed and implemented nonrecursively by Lee (Naval Research Laboratory Report 8192, March 1978). Calculations show that the proposed recursion introduces considerable improvement in efficiency as it reduces the number of computations required to process a given set of pixels.
