A fast algorithm for local minimum and maximum filters on rectangular and octagonal kernels

Research output: Contribution to journalArticle


A new algorithm is presented for local maximum and minimum filters requiring only 6 comparisons per pixel independent of kernel size. The algorithm is based on separability and a combination of block recursive series which are evaluated forwards and backwards.
