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。 我们的方法也明显快于之前最好的 CNN 流方法(FlowNet),FlowNetS 的运行...
A large dataset to train convolutional networks for disparity, optical flow, and scene flow estimation. In IEEE Conference on Computer Vision and Pattern Recognition (CVPR) , 2016. [17] B. D. Lucas and T. Kanade. An iterative image registration technique with an application to stereo vision...
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 ...
