Abstract
Grey-level transformations on digitized images are variously used to minimize storage requirements or to enhance low-level contrast information. A graph-theoretic approach is proposed to implement these transformations. In particular, an efficient algorithm is given for transformation leading to almost uniform grey-level distribution.Keywords
