The present book is concerned with a classical problem in signal processing, namely signal enhancement. The problem can be defined as follows: given an observed, noisy signal find, somehow, an estimate of the desired signal. In many applications, th
Automatic Color Enhancement "ACE" is an effective method for color image enhancement introduced by Gatta, Rizzi, and Marini based on modeling several low level mechanisms of the human visual system. The direct computation of ACE on an NxN image cost
比较新的对比度增强论文，论文《CONTRAST ENHANCEMENT BASED ON LAYERED DIFFERENCE REPRESENTATION》是一种思路比较新颖的利用直方图思想来进行对比度增强的算法，经常在低光增强的算法比较中见到。其核心思想是重建映射函数X=[$x_{0\sim255}$],X由差分变量d来构建。
