Webb21 feb. 2024 · In this study, we propose a deep learning-based spatial refinement method to provide robust high-resolution velocity fields for particle image velocimetry (PIV) analysis. We modified the architecture of the convolutional neural network (CNN)-based optical flow model, FlowNet2, to receive the subdomain of particle image pair and … WebbThe Slow pathway (Fig. 1, top row) is a convolutional network that processes videos with a large temporal stride ( i.e ., it samples one frame out of τ frames). The primary goal of Slow pathway is to produce features that capture semantic contents of the video, which has a low refreshing rate (semantics do not change all of a sudden).

Webbcompute optical flow, and therefore, our models are learned end-to-end from the raw data. In our experiments we observe that the SlowFast network is empirically more effective. Our method is partially inspired by biological studies on the retinal ganglion cells in the primate visual system [27, 37, 8, 14, 51], though admittedly the analogy is ...
