一个用于转换bmp 文件格式的程序， 可转换成单色的bmp图像。-One for the bmp file format conversion process, can be converted into monochrome bmp images.

利用数字水印技术能够对数字作品实现有效的版权保护。目前的数字水印技术大多都是针对多媒体数据。但是在地理信怠系统中除了橱格数据外, 还存在大的矢童数据。目前的数字水印算法仅仅能满足橱格数据, 无法满足在矢童数据中嵌入水印的需求。本丈在分析数据特汽的基础上, 在矢童数据的频城提出了一套行之有效的数字水印算法。-The use of digital watermarking technology for digital works to achieve an effective copyright protection. At present, most of the digital watermarking technology are targeted at multimedia data. However, in the geographical letter except idle system cabinet grid data, there are still a big child vector data. At present, only the digital watermarking algorithm can satisfy the cupboard grid data, unable to meet the child in the vector data embedded watermark needs. Zhangting data in the analysis of this special steam on the basis of the data in the frequency of vector Tong City proposed a set of proven digital watermarking algorithm.

摘要：拐点是数字图像中的一个重要信息载体 提出一种新的拐点检测算法 该算法并非寻找连续空间中曲率的离散近似计算方法，而是源于离散曲线的外观特征，推导出离散曲线上拐点处k个点对间欧氏距离平方和局部最小这一重要性质。基于该性质，本算法首先利用Freeman链码的性质.过滤掉物体边界上明显不可能成为拐点的象素，然后在剩余的边界点中通过寻找该局部最小值定位出拐点。给出了本算法与四种著名拐点检测算法的对比实验。 -Abstract: The inflection point is a digital image of an important information carrier put forward a new turning point detection algorithm the algorithm does not look for continuous space discrete approximation of the curvature calculation method, but from the appearance of characteristics of discrete curve derived discrete curve the inflection point at k-points between the squared Euclidean distance and the local minimum of this important property. Based on the nature of the algorithm is the first to use Freeman chain code in nature. Filter out objects clearly can not become a turning point on the border pixel, and then in the remaining boundary points by finding out the turning point of the local minimum position. The algorithm is given inflection point detection algorithm with th
