- 人脸视频图像编码是近年来图像编码领域里的一个研究热点问题,它在通信、互联网等方面有着广泛的应用前景。人脸图像编码的研究包含很多子问题,主要的三个方面为:精确的人脸目标定位算法,实时的人脸目标跟踪算法和高效的人脸图像编码方法。本文的主要研究工作在于: 1) 提出帧间差分和背景差分相结合的人脸目标定位算法,在人脸特征选择上,主要使用形状特征,通过椭圆拟合来得到人脸的位置。 2) 采用基于Kalman滤波的运动预测方法对人脸的区域变化进行预测,以此缩小目标可能存在的区域(ROI).-Facial vi

- 用帧差分可以检测场景变化,一个简单帧差分可通过计算两个连续帧的象素获得。对帧内每个象素点(x,y),T时刻与T-1时刻象素值之差为Dx,y(T)=||Sx,y(T) – Sx,y(T-1)||。设定内帧差分系数IDsum=ΣL , IF ||Sx,y(T) – Sx,y(T-1)||≥Ta THEN L=TRUE,实际决定是否报警,可以通过计算三帧以上IDsum数量-Frame difference can be detected with the scene changes, a simple

- 三帧差分算法是相邻两帧差分算法的一种改进方法,它选取连续三帧视频图像进行差分运算,消除由于运动而显露背景影响,从而提取精确的运动目标轮廓信息。该算法的基本原理是是先选取视频图像序列中连续三帧图像 并分别计算相邻两帧的差分图像,然后将差分图像通过选取适当的阈值进行二值化处理,得到二值化图像,最后在每一个像素点得到的二值图像进行逻辑与运算,获取共同部分,从而获得运动目标的轮廓信息。-Three differential algorithm is an improved method of two
