色彩空间转换，支持RGB, YUV, HSV, HSL, Lab, Luv等格式-Color space conversion, support for RGB, YUV, HSV, HSL, Lab, Luv, etc. formats

C++编写的医学用的细胞识别统计系统,可以腐蚀膨胀,平滑,最后统计出细胞个数.

在计算机视觉中首先一步是计算每个摄像机的参数(外参和内参)，这是重建物体所必须的，这一个过程称为摄像机定标(camera calibration)。这是我自己写的一个简单的采用3维模板(模板是由黑白相间的格子组成，格子大小30cm×30cm，模板必须是三维，否则矩阵奇异)定标的程序，交互性比较好，每个角点通过鼠标点击自动获取。-Computer Vision in the first step is to calculate the parameters of each camera (outside the Senate and internal), which is necessary for the reconstruction of objects, which a process known as camera calibration (camera calibration). This is what I wrote it myself using a simple 3-dimensional template (template is composed of black-and-white lattice, lattice size of 30cm ?30cm, the template must be three-dimensional, or matrix singular) calibration procedures, better interactivity, each Corner automatic access through mouse clicks.

不同方式的多边形填充-different forms of Polygon Fill

TIDSP DM642上用的图像锐化程序-TIDSP DM642 use the image sharpening process

数字图像腐蚀程序。参数中有一个BOOL变量， 为真时，表示在水平方向进行腐蚀运算，否则在竖直方向上进行腐蚀运算。-digital image corrosion process. Parameters have a BOOL variable to true, in the horizontal direction corrupting computation, Otherwise, the vertical direction on erosion.

（1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象； （2）将所有子图象按列相接变成一个81维的行向量； （3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量； （4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。 （5）求出所有子块的特征向量。 -(1) the application of 9 × 9 window of these images at random, a total sample of 200 sub-image (2) all sub-images according to out-phase into a 81-dimensional row vector (3) all 200 lines for KL transform vector, derived its corresponding covariance matrix of eigenvectors and eigenvalues, in descending order by eigenvalue and the corresponding eigenvector (4) a choice to 40 corresponding to the largest eigenvalue eigenvector as the PCA, the original image block to the 40 feature vectors on the projection, the projection coefficients obtained by this sub-block eigenvector. (5) calculated for all sub-block eigenvector.

几个程序，Wallis变换，DCT变换，形态学操作-several procedures, Wallis transform, DCT, morphological operations

用opencv实现的人脸检测功能，以及自己编写的代码实现人脸检测功能-Achieved with opencv face detection function, as well as their own code written in the realization of human face detection function

这是一个种子填充算法，是根据已知的一个多边形区域内部的一个象素点来找到区域内其他的象素点进行填充的。-This is a seed fill algorithm is based on a polygon known within the region point to a pixel within the region to find other pixel sites filled.
