Webframe-based algorithms, the correlation layer (Ilg et al. 2024) has been shown to provide important cues for opti-cal flow estimation. But it has been missed in all the previ-ous event-based work since it cannot extract features from one entity input. Unlike previous work (Zhu et al. 2024; Ye et al. 2024; Zhu et al. 2024b), STE-FlowNet processes 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 …

Because there exists a huge semantic gap between higher-level layer and lower-level layer, explicit correspondence calculation on such features is difficult and tends to fail for offset prediction. Moreover, adopting ... biotherm codice sconto

WebMay 29, 2024 · The idea of utilizing the correlation layer is inspired by Flownet , in which the correlation layer is used to match feature points between frames for optical flow estimation. Our motivation of using the correlation layer is to filter the heat-maps (high-level features), which are generated separately for each input image, to highlight the heat ...
