Face Detection using Viola-Jones Algorithm

求图像在hsv颜色空间下三个通道的颜色矩(colormoment in hsv colorspace)

对特征值进行非极大值抑制的角点检测，并且选用了合适的阈值加强检测效果(corner detection by non-maxima suppression of Eigenvalues and selected the appropriate threshold to enhance detection)

说明：  图像稀疏编码的一种方法，可用于基于稀疏表示的图像压缩、去噪等(Sparse image coding method can be used for sparse representation-based image compression, denoising, etc.)

低对比度图像小目标识别,top-hat.海平面小目标(荧光轨迹,舰船)识别(top-hat, dim small target detecting)

这是一个sar成像的算法，它融合了cfar的处理，使目标更加凸显。非常适合用于sar成像和cfar算法的研究。(This is a sar imaging algorithm, which combines cfar processing, the target is more prominent. Very suitable for research sar algorithm for imaging and cfar.)

free-vision library,计算机视觉C++库，含有SAMPLE,非常经典！(free-vision library, computer vision C library, containing SAMPLE. very classic!)

说明：  DOG高斯差分实现物体识别中的特征提取,对不同尺度空间的图像进行差分，从而获得描述物体的特征值(difference of gaussian to achieve the feature point exaction of object recognition)

gray image to color image conversion

说明：  该文件主要用于减少相干斑噪声，包含各种常见的滤波器如Lee滤波器，Frost滤波器等(This file is mainly used to reduce speckle noise, including a variety of common filters, such as Lee filter, frost filter and so on)

　　本函数选用阈值分割的方法来完成瞳孔定位。根据图像的灰度分布特性，瞳孔部分的灰度值最小，其次为虹膜部分，最大的为巩膜部分。因此在灰度直方图中，第一个大峰值的邻域即是瞳孔所在区域。(Function selects the threshold segmentation method to accomplish the pupil location. Based on image gray distribution features, the pupil part of the grey value of the minimum, followed by the iris part, the biggest part of sclera. So in gray level histogram, the peak value of the first big neighborhood is the pupil area.)
