An algorithm is presented for digital image processing based on local statistics. The algorithm constitutes a recursive implementaiton of an approach proposed and implemented nonrecursively by J.S. Lee (Naval Research Laboratory Report 8192, March 1978). Calculations show that the proposed recursion introduces considerable improvement in efficiency.
