What is Optical Flow and why does it matter in deep learning

Webing [60] computes the correlation of image patches to ﬁnd dense correspondence to improve optical ﬂow. Unlike deep matching using hand-crafted features, FlowNet [11] is a network, where a correlation layer performs multiplicative patch comparisons. Correlation layers were also used in other CNN-based optical ﬂow algorithms [48, 23]. Besides WebFlowNet. Optical flow , 是根据两个观测瞬间之间的物体表面、形状等的变化从而，计算出物体运动变化的一种方法。. CNN，因为CNN的capability 足够强大，所以可能通过 train 大量的data-label 的数据，train出一个CNN来学习data与label 之间的关系。. 在一个video中给出 … Web（1）FlowNet-S.
