DGHM中灰度变换函数的四种构造模型

Four Constructions of the Gray-Level Translation for DGHM

文章从理论上对数学图象增强技术中的DGHM进行了系统阐述 ,进而提出了四种灰度级变换函数构造模型。

In this paper,the theoretic explanation about DGHM,one of the gray-level histogram modification techniques,are put forward. Furthermore,four constructions of the gray-level translation are modeled.
