人脸跟踪的一些主流算法的matlab实现(face tracking algorithm for the mainstream to achieve the Matlab)

实现RGB颜色空间到HSV颜色空间变换的函数。(achieve RGB color space to the HSV color space conversion function.)

说明：  用matlab做彩色图像的二维直方图，比如rb、rg、bg等(use matlab to draw colour image histogram of two dimension )

可以快速准确的找出光斑、或者任何椭圆形状二值图像的质心(The center of mass of a two value image can be quickly and accurately identified.)

KSVD算法的工具包，安装在matlab的相关路径下，可以直接调用。(KSVD algorithm Kit installed in the path of matlab can be called directly.)

说明：  基于相位梯度法PGA的 Matlab 估计相位误差 估计多普勒中心(Estimation of Phase Error and Doppler Center by PGA MATLAB)

由于图像在经过一次 JPEG 压缩和双重 JPEG 压缩之后其 DCT 系数具有一定的相关性，通过对这种相关性进行分析，提出了一种基于 JPEG 图像双重压缩特性的图像篡改检测算法，并用此算法检测图像是否经过篡改和定位篡改区域。 (Since the image after a first JPEG compression JPEG compression and double its DCT coefficients having some relevance, by this correlation is analyzed, and an image based on JPEG image compression characteristic double tamper detection algorithm, and the algorithm used to detect whether the image been tampered with and locate the tampered areas.)

demons 配准非常好用的非刚体配准！(Registration is very easy demons non-rigid registration!)

基于暗通道先验理论的去雾算法，使用rgb暗通道计算大气光及透射率获得去雾图像(Since the scene radiance is usually not as bright as the atmospheric light, the image after haze removal looks dim. So we increase the exposure of J(x) for display.)

转载一个基于FCM的图像分割matlab源代码，初学者可以参考。(Reprint of an FCM-based image segmentation matlab source code, can refer to beginners.)
