Gray-scale image enhancement using the SMQT
Markus Nilsson, Mattias Dahl, Ingvar Claesson · 2005
This paper explores the successive mean quantization transform (SMQT) for automatic enhancement of gray-scale images. The transform is in the paper presented using set theory. The image enhancement capabilities and properties of the transform are analyzed. The transform is capable to perform both a nonlinear and a shape preserving stretch of the image histogram. Experiments and comparisons to histogram equalization are conducted.
