qtrack_090
- QTrack是使用opencv库编写的面部追踪系统。性能比使用camshift的系统要好-QTrack is a face tracker for use with OpenCV. QTrack is both faster and more robust than OpenCV s Camshift for tracking faces. QTrack version 0.90 was written by Robin Hewitt and is distributed un

- 利用opencv对矩阵进行的运算操作等,可以产生服从均匀分布的随机矩阵,也可以产生服从正态分布的随机矩阵,有矩阵乘法,加法,除法等,非常方便,可以直接拿来用的。-Using opencv on computing matrix operations, etc., can produce uniformly distributed random matrix, can also produce a normal distribution of random matrices, a matrix m
Histogram-equalization
- 如果一副图像的像素占有很多的灰度级而且分布均匀,那么这样的图像往往有高对比度和多变的灰度色调。直方图均衡化就是一种能仅靠输入图像直方图信息自动达到这种效果的变换函数。它的基本思想是对图像中像素个数多的灰度级进行展宽,而对图像中像素个数少的灰度进行压缩,从而扩展像原取值的动态范围,提高了对比度和灰度色调的变化,使图像更加清晰。-If an image pixel occupies a lot of gray level and evenly distributed, so such images
