StreamFlow: Streamlined Multi-Frame Optical Flow Estimation for Video Sequences

Posted by dbos Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Occlusions between consecutive frames have long posed a significant challenge in optical flow estimation. The inherent ambiguity introduced by occlusions directly violates the brightness constancy constraint and considerably hinders pixel-to-pixel matching. To address this issue, multi-frame optical flow methods leverage […]

A Geometric Tension Dynamics Model of Epithelial Convergent Extension

Posted by dbos UCSB

Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman, , | Summary: Epithelial tissue elongation by convergent extension is a key motif of animal morphogenesis. On a coarse scale, cell motion resembles laminar fluid flow; yet in contrast to a fluid, epithelial cells adhere to each other […]

X-ray Polarization of the Eastern Lobe of SS 433

Posted by dbos MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Philip Kaaret, Riccardo Ferrazzoli, Stefano Silvestri, Michela Negro, Alberto Manfreda | Summary: How astrophysical systems translate the kinetic energy of bulk motion into the acceleration of particles to very high energies is a pressing question. SS 433 is a microquasar that emits TeV gamma-rays indicating the […]

Self-Supervised Learning of Whole and Component-Based Semantic Representations for Person Re-Identification

Posted by dbos UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Siyuan Huang, Yifan Zhou, Ram Prabhakar, Xijun Liu, Yuxiang Guo | Summary: Person Re-Identification (ReID) is a challenging problem, focusing on identifying individuals across diverse settings. However, previous ReID methods primarily concentrated on a single domain or modality, such as Clothes-Changing ReID (CC-ReID) and video ReID. Real-world […]
