A technique for the contrast enhancement of a picture is proposed. The method is derived from the entropy concept of information theory. The originality of the algorithm rests on the use of a local contrast to define the digital entropy. The basic idea of the treatment is to enhance the contrast by transforming the global entropy. The same technique can also be used for an adaptive smoothing processing.
提出了一种用于增强图像对比度的技术。该方法源自信息论的熵概念。该算法的新颖之处在于使用局部对比度来定义数字熵。处理的基本思想是通过变换全局熵来增强对比度。该技术还可用于自适应平滑处理。
