Wenhuan Gao · Hedianzixue yu tance jishu · 2005
Contrast enhancement of images is one of the major issues in image processing, especially radiological images. In this paper a kind of new algorithm that combines unsharp masking, adaptive nonlinear filters and mathematical morphology is presented. Compared to the existing techniques, the proposed method has good effects on processing radiological images. Furthermore, it can preserve as much edge information as possible.
