Video synopsis aims at providing condensed representations of video data sets that can be easily captured from digital cameras nowadays, especially for daily surveillance videos. Previous work in video synopsis usually moves active objects along the time a...
 
Fast Exact Nearest Patch Matching for Patch-Based Image Editing and Processing
Found in: IEEE Transactions on Visualization and Computer Graphics
By Chunxia Xiao, Meng Liu, Yongwei Nie, Zhao Dong
Issue Date:August 2011
pp. 1122-1134
This paper presents an efficient exact nearest patch matching algorithm which can accurately find the most similar patch-pairs between source and target image. Traditional match matching algorithms treat each pixel/patch as an independent sample and build ...
 
Efficient Edit Propagation Using Hierarchical Data Structure
Found in: IEEE Transactions on Visualization and Computer Graphics
By Chunxia Xiao, Yongwei Nie, Feng Tang
Issue Date:August 2011
pp. 1135-1147
This paper presents a novel unified hierarchical structure for scalable edit propagation. Our method is based on the key observation that in edit propagation, appearance varies very smoothly in those regions where the appearance is different from the user-...
