虽然系统有给出划圆的直接的函数，但是没有让读者了解具体的计算机系统内部的绘制过程，本程序以顺圆为例，以逐点逼近法画出了并且是可以从任意点开始的顺圆的程序-Although the system is given a round of direct function, but did not allow the reader to understand the specific computer systems within the mapping process, the procedures to Shun Yuen example, the point-by-painted with the approximation and can be started from any point of Shun Yuen procedures

提出一种新的非线性变换的彩色空间 ″″, 利用次高斯概率分布函数拟合皮肤色度信息, 得到候选区 YC C r b 域。为了排除候选区域中的非人脸, 首先根据均值和方差信息分割出候选区域中的纹理特征信息, 再通过多尺度 ) ( 信息定位眼睛, 然后根据人脸特征的几 形态边缘检测算子检测候选区域的边缘, 利用 边缘方向 PCA PCAED ( ) 何形状信息定位其他特征 鼻、嘴 , 通过这些几何特征信息对肤色分割得到的候选区域进行验证, 最终得到正确 的人脸区域。利用3 个实验数据集测试该算法, 并与其它相应的算法相比较, 提出的非线性彩色空间对于肤色分 割具有很好的效果, 且对光照和姿态具有良好的不变性。另外, 利用 信息和几何特征信息检测人脸特征 PCAED 具有很高的定位精度, 定位检测率优于其他方法。实验结果表明, 该算法具有定位准确率高, 漏检率和误检率低 等特点。- A novel approach for skin segmentation and facial feature extraction is proposed The proposed skin segmentation is a method for integrating the chrominance components of ″″ . ″″ r b r b nonlinear YC C color model The chrominance components of nonlinear YC C color space , are modeled using a subgaussian probability density function and then the face skin is seg . , mented based on this function In order to authenticate the face candidate regions firstly tex ture information in face candidate regions is segmented using mean and variance of luminance ,

用于绘制基础bezier curve,4点可以控制一跳曲线,4点之后再次点击鼠标会重新出现控制点.-used to draw sample bezier cuve, it support the bezier curve that has 4 control points.

主要功能简介：1、支持完全在线维护。可以在线完成新建/删除相册、更新图片、删除图片、更改名称等所有操作。上传之后完全可以不依赖FTP软件来维护相册。2、缓存更新功能使得批量更新图片/相册更为容易。你只需要把所有需要更新的图片一次上传到相应文件夹，然后进入后台操作点击“更新缓存”，相册的所有数据都将自动更新。3、在GD库的支持下，图片的缩略图完全自动生成。你所要做的只是上传图片到相应相册，支持的图片格式有 jpg/jpeg,gif,png,bmp。（由于GD不支持bmp格式，所以bmp的图片不能生成缩略图）需要GD2的支持，支持的图片格式有 jpg/jpeg,gif,png,bmp -major profiles : one, to support the total online maintenance. Complete the online add/delete photo albums, updated pictures, delete pictures, names and other changes all operations. After uploading can not rely on FTP software to safeguard albums. 2 cache update feature allows batch update Photo/albums easier. You should only need to update all the pictures uploaded to a corresponding folder, and then click into the background of operation "update cache," albums of all data will be automatically updated. 3, in the GD library, with the support of the thumbnail pictures fully automatic generation. You just have to upload pictures to the corresponding photo albums, the support photo forma
