对于纹影,很多人往往认为是一种定性的流动显示方法(也许之前是)。但是,随着高速相机的发展和图像处理算法的进步,以及广大科研工作者的不懈努力,近年来,我们能够将‘定性‘的方法‘定量化’。Optical Flow是一种图像处理算法,但是与纹影相结合,便碰撞出了火花,让我们可以计算出流场的速度! 最近,王倩老师团队发展了基于...
Optical Flow是一种图像处理算法,但是与纹影相结合,便碰撞出了火花,让我们可以计算出流场的速度! 最近,王倩老师团队发展了基于纹影特性方程的改进光流算法,显著提升了纹影测速的精确度和鲁棒性。光流算法,顾名思义,是通过追踪两帧图像像素点亮度的流动,来获取空间点的二维运动速度场。这个原理就是亮度守恒约束,建立了...
The optical flow is estimated as the motion between two consecutive video frames. The video frame T at the given instant tcurrent is referred as current frame and the video frame T-1 is referred as previous frame. The initial value of the previous frame at time tcurrent = 0 is set as ...
