- 一种嵌入可读水印的自适应盲水印算法, 本文提出了一种基于DWT的嵌入可读水印的自适应盲水印算法,通过分析图像经离散小波变换后细 节子带系数的特性,把细节子带系数的均值和方差作为水印信息的一部分来自适应地修改图像小波分解后某些细节 子带的系数值,在满足水印不可感知性的条件下自适应地嵌入水印信息,实现了水印不可感知性和鲁棒性之间的折 衷. 同时,水印的提取无须求助于原图像,很好的实现了水印的盲检测. 这里的水印是一幅有实际意义的二值图像. 实 验结果和攻击测试表明,本文提出的算

- 直方图及直方图均衡化,用来增加许多图像的局部对比度,尤其是当图像的有用数据的对比度相当接近的时候。通过这种方法,亮度可以更好地在直方图上分布。这样就可以用于增强局部的对比度而不影响整体的对比度,直方图均衡化通过有效地扩展常用的亮度来实现这种功能。 -Used to increase the local contrast of many images, especially when the contrast of the image of the useful data is very c

- 直方图均衡,图像去雾处理,是把原始图像的灰度直方图从比较集中的某个灰度区间变成在全部灰度范围内的均匀分布。直方图均衡化就是对图像进行非线性拉伸,重新分配图像像素值,使一定灰度范围内的像素数量大致相同。-Histogram equalization, image processing to the fog, is the original image histogram to a gray scale from the more concentrated into the full range o

- 灰度直方图是灰度级的函数,描述的是图像中具有该灰度级的像素的个数。它是多种空间域处理技术的基础。直方图操作能够有效用于图像增强;提供有用的图像统计资料,其在软件中易于计算,适用于商用硬件设备。直方图均衡化是通过对原图像进行某种变换,使原图像的灰度直方图修正为均匀分布的直方图的一种方法。图像灰度 直方图均衡化使得图像的灰度分布趋向均匀,图像所占有的像素灰度间距拉开,加大了图像反差,改善了视觉效果,达到增强目的。MATLAB是数字图像处理的常用工具,应用MATLAB的各种函数能够对数字图像进行各种处
