运用信息论的知识求解图像的信息量也就是熵的算法。-use of information, the knowledge to solve image is the amount of entropy algorithm.

很多几何图形的画法，如三维图形、曲线及曲面的绘制，三次样条曲线，BEYOND，曲面，Beziel曲线等--Many geometric figure drawing methods, like three dimensional graph, curve and curved face drawing, three transects tunes curve, BEYOND, curved surface, Beziel curve and so on

二维几何变换，包括图像的平移变换、切磋变换、缩放变换、旋转变换-Two-dimensional geometric transformations, including the image of the translation transformation, Qiecuo transform, scale transform, rotation transformation

GIS简单的图形系统，可以兼容DWG等矢量数据-GIS simple graphical system that is compatible with DWG vector data, etc.

一个vc编的八叉树算法，八叉树常用于3维图形的之间的干涉问题，-A vc series octree algorithm, Octree commonly used in the 3-dimensional graphics of the interference between the issues,

程序说明: //该函数用来对图像进行阈值变换。对于灰度值小于阈值的象素直接设置 灰度值为0；灰度值大于阈值的象素直接设置为255。-procedures :// This function used to image transform threshold. For gray value less than the threshold value of the pixel intensity value directly set to 0; Gray value greater than the threshold value of the pixel is set to direct 255.

通过matlab自带的edge函数求图像边缘 然而单一的算子得到边缘较浅 可以通过三个效果相似的算子sobel,prewitt,roberts得到的边缘加起来
