In this chapter we review the estimation of the two-dimensional apparent motion field of two consecutive images in an image sequence. This apparent motion field is referred to as optical flow field, a two-dimensional vector field on the image plane. Because it is nearly impossible to cover ...

GPU-flow[43]开启了这一趋势,但现在有几种方法的性能超过了它。PCA-Flow[44]在 CPU 上运行,速度慢于帧速率,产生的流场过于平滑。EPPM [5] 在 Sintel(测试)上实现了类似的中等性能,在 GPU 上也有类似的速度。最近,DIS-Fast [26] 是一种 GPU 方法,其速度明显快于之前的方法,但精确度也明显较低。 我们的...
Optical flow estimation is important as the basic element of the model is optical flow vectors. As mentioned in Section 4, detection of features and estimation of optical flow according to these features are the main steps of optical flow estimation. The methods and approaches for both steps ...
Flow regularization cascaded 光流推断类似于能量最小化方法中的数据正则化。仅使用数据项,光流中会出现模糊的 flow boundaries 和不受欢迎的假象。为解决这一问题,通常使用 local flow 方向一致性以及光流方向边界和亮度边缘之间的共现作为正则化光流的线索。一些代表性的方法包括各向异性图像驱动法[32]、图像和光...
