对比度

This paper presents a new methods that enhance the image of hand vein based on contrast limited local histogram equalization and top-hat transform to overcome the influence of photoelectric and thickness of the back of hand skin.

为了克服光强，手背厚度对手背静脉图像的影响，提出一种新的手背静脉图像增强方法，对比度受限的局部直方图均衡和top-hat变换相结合的方法。

We propose a novel method to obtain speckle fringe patterns of ESPI from undeformed and deformed speckle patterns.

由我们方法获得的条纹图比减条纹有更高的对比度和更好的质量，新方法是简单的，不需要复杂的计算。

human visual perception ; unitary rectuit transform ; prewitt operator filtering ; standerd deviation enhancement ; median filtering

这个方法可以同时增强整个图像对比度和边缘，但它的缺点是对噪声敏感，会非线性地增强图像的

Also, it didn't always perform up to snuff, particularly in images with high contrast shot at ISO 400 and above.
