Because of the decoupling of the velocity and the pressure computation,the projection method is much more efficient than the fully coupled procedures.
在过去的20多年中,投影方法通过速度和压力的解耦计算,获碍了比全耦合方法更高的计算效率,这个显著优点使之得以广泛应用。
Then by using edge detection, Hough transformation, template matching and variance projection, facial features such as eyes, nose and mouth are located quickly and effectively.
通过区域增长从人脸图像中分割出人脸 ,再利用边缘检测、Hough变换、模板匹配和方差投影技术可以快速有效地提取出人脸面部器官眼睛、鼻子和嘴巴特征 。
Finally the center of eye can be precisely given by variance projection and binaryzation.
首先利用一种多尺度自商图方法消除人脸图像的光照影响;然后综合运用形态学操作的开闭运算提升眼睛区域特征并采用相关系数法获得眼睛粗定位,对开闭眼不敏感;最后对粗定位区域进行方差投影并二值化后获得精确的眼睛中心点。
