Classifying dynamic textures via spatiotemporal fractal analysis

Yong Xu, Yuhui Quan, Zhuming Zhang, Haibin Ling, Hui Ji
2015 Pattern Recognition  
Dynamic texture (DT) is essential for understanding the video sequences with spatio-temporal similarities.  ...  To fully exploit various types of dynamic patterns in DT, five measurements of DT pixels are collected for the analysis on DT sequences from different perspectives.  ...  To efficiently extract local DT patterns, many methods have been proposed, e.g. the spatio-temporal filtering for specific motion patterns [13, 14] , the spatiotemporal extensions of local binary pattern  ...

A 3D Simplification Method based on Dual Point Sampling

Juan Cao, Yitian Zhao, Ran Song, Yingchun Zhang
2013 Journal of Multimedia  
Digital watermarking has been widely used in copyright protection for digital images, but most of the watermarking algorithm can't resist print-and-scan process.  ...  The watermark information is embedded in a halftone process for image screening with phase modulation method. The watermark is extracted by a template, which is optimized using the PSO algorithm.  ...  We also thank the anonymous reviewers for their suggestions and feedback that helped us to improve the quality of this paper.  ...
