Interactive Removal and Ground Truth for Difficult Shadow Scenes
Han Gong, Darren P. Cosker
A user-centric method for fast, interactive, robust and high-quality shadow removal is presented. Our algorithm can perform detection and removal in a range of difficult cases: suc…
Video Interpolation using Optical Flow and Laplacian Smoothness
Wenbin Li, Darren Cosker
Non-rigid video interpolation is a common computer vision task. In this paper we present an optical flow approach which adopts a Laplacian Cotangent Mesh constraint to enhance the…
Blur Robust Optical Flow using Motion Channel
Wenbin Li, Yang Chen, JeeHang Lee +2
It is hard to estimate optical flow given a realworld video sequence with camera shake and other motion blur. In this paper, we first investigate the blur parameterization for vide…
Drift Robust Non-rigid Optical Flow Enhancement for Long Sequences
Wenbin Li, Darren Cosker, Matthew Brown
It is hard to densely track a nonrigid object in long term, which is a fundamental research issue in the computer vision community. This task often relies on estimating pairwise co…
Nonrigid Optical Flow Ground Truth for Real-World Scenes with Time-Varying Shading Effects
Wenbin Li, Darren Cosker, Zhihan Lv +1
In this paper we present a dense ground truth dataset of nonrigidly deforming real-world scenes. Our dataset contains both long and short video sequences, and enables the quantitat…
