• 对数变换 - 引用次数：3

  The methods based on gray-level mapping, for instance, histogram Equalization, logarithm transform,γ-Correction, are defective since the resultant images are unnatural in grey level transition and short of three-dimensional sense.

  基于灰度映射如直方图均衡化、对数变换、γ-校正等方法出现效果图层次过渡不自然,缺乏立体感等问题。
