运动估计是视频编码的关键技术,其最基本的原理是利用相邻帧间的时间
相关性,通过预测来减少时间冗余度。在实际编码中,为了节省码率,并不传
输每一帧的全部数据,而是利用运动估计求出每一帧与其预测参考帧之间的差
值。运动估计越准确,差值的分布越趋近与零,差值块的能量越小,经过变换、
量化和熵编码后所产生的码流的比特位率也越少。因此,运动估计搜索的准确
程度直接影响到了编码的压缩性能。

1.基本内容
本设计目标在于利用Matlab强大的图像处理能力和实用便捷的编程方法,通过处理包含人脸的视频帧系列图像,灰度积分投影技术的眼睛定位方法,进而利用perclos计数,计算眨眼率,从而得到比较准确的疲劳状况。
2.具体要求
本设计基于灰度积分投影技术的眼睛定位方法,再结合perclos技术。首先通过图像预处理技术得到灰度分配较为均匀的图像,然后分别利用水平和垂直灰度积分投影曲线结合人脸的结构特征找到眼睛的位置坐标,实现了准确的眼睛定位,通过perclos技术技术眨眼率,根据先
