Description: matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如未修改，可提取隐藏信息。当有修改发生时，可以定位修改的位置，并在图上标出。标识面积占修改面积的75％，一般修改都能标出-matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, if modified, can extract hidden information. When a modification occurs, you can modify the location of positioning and marked maps. Logo area accounted for 75 to amend the area generally can be identified modifications

Description: 图像细化 （Image Thinning），一般指二值图像的骨架化（Image Skeletonization） 的一种操作运算。
一个图像的骨架由一些线和曲线（比较理想的是单像素宽度），骨架可以提供一个图像目标的尺寸和形状信息，因而在数字图像分析中具有重要的地位，图像细化（骨架化）是进行图像识别、线条类图像目标分析的重要手段。
本文将探讨骨架的一些性质，给出如何判断一个像素是否属于图像目标的骨架，最后将给出获得图像目标骨架的基本算法。-Image Thinning (Image Thinning), generally refers to binary image of the skeleton (Image Skeletonization) an operation of computing. An image of the skeleton by a number of lines and curves (more ideal is a single pixel width), can provide a skeleton image target size and shape information, which in the digital image analysis in an important position, image thinning (skeleton of) is image recognition, line-type image of an important means of target analysis. This article will explore some properties of the skeleton is given how to determine whether a pixel belongs to the target image of the skeleton, the final goal will be given access to images of the basic algorithm skeleton.
