WebFlowNet Correlation. FlowNetCorr extracts features from each image independently for the first three convolution layers. It then finds the correlation between each "patch" of image 1 and each "patch" of image 2. The feature maps are then replaced with correlation values. To reduce computational intensity, correlations with displacement D are ...

FlowNet: Learning Optical Flow with Convolutional Networks

WebApr 26, 2015 · In this paper we construct appropriate CNNs which are capable of solving the optical flow estimation problem as a supervised learning task. We propose and compare two architectures: a generic architecture and another one including a layer that correlates feature vectors at different image locations. Webing [61] 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 [49,24]. Besides flower shops in pamplico sc
