ScanFocus: A Coarse-to-Fine Framework for Spatio-Temporal Video Grounding
Kai Chen, Ming Dai, Wenxuan Cheng +1
The paper introduces ScanFocus, a coarse-to-fine framework for spatio-temporal video grounding that first scans videos globally to generate coarse object proposals and then refines…
DeRIS: Decoupling Perception and Cognition for Enhanced Referring Image Segmentation through Loopback Synergy
Ming Dai, Wenxuan Cheng, Jiang-jiang Liu +4
Referring Image Segmentation (RIS) is a challenging task that aims to segment objects in an image based on natural language expressions. While prior studies have predominantly conc…
Effective transport by 2D turbulence: Vortex-gas theory vs. scale-invariant inverse cascade
Julie Meunier, Basile Gallet
The scale-invariant inverse energy cascade is a hallmark of 2D turbulence, with its theoretical energy spectrum observed in both direct numerical simulations (DNS) and laboratory e…
SpatialBot: Precise Spatial Understanding with Vision Language Models
Wenxiao Cai, Iaroslav Ponomarenko, Jianhao Yuan +4
Vision Language Models (VLMs) have achieved impressive performance in 2D image understanding, however they are still struggling with spatial understanding which is the foundation o…
Precise GPS-Denied UAV Self-Positioning via Context-Enhanced Cross-View Geo-Localization
Yuanze Xu, Ming Dai, Wenxiao Cai +1
Image retrieval has been employed as a robust complementary technique to address the challenge of Unmanned Aerial Vehicles (UAVs) self-positioning. However, most existing methods p…
Object-level Geometric Structure Preserving for Natural Image Stitching
Wenxiao Cai, Wankou Yang
The topic of stitching images with globally natural structures holds paramount significance, with two main goals: pixel-level alignment and distortion prevention. The existing appr…
