UPFlow: Upsampling Pyramid for Unsupervised Optical Flow Learning
TL;DR: This work designs a self-guided upsample module to tackle the interpolation blur problem caused by bilinear upsampling between pyramid levels, and proposes a pyramid distillation loss to add supervision for intermediate levels via distilling the finest flow as pseudo labels.
Journal ArticleDOI
Unified cardinalized probability hypothesis density filters for extended targets and unresolved targets
TL;DR: In this article, a unified cardinalized probability hypothesis density (CPHD) filter for extended targets and unresolved targets is proposed, and theoretically rigorous measurement update equations for the proposed filters are derived according to the theory of random finite set (RFS) and finite-set statistics (FISST).
Journal ArticleDOI
Discrete Conformal Deformation: Algorithm and Experiments
TL;DR: In this article, the authors introduce the definition of discrete conformality for triangulated surfaces with flat cone metrics and describe an algorithm for solving the problem of prescribing curvature, which is to deform the metric discrete conformally so that the curvature of the resulting metric coincides with the prescribed curvature.
