Contour extraction of gait recognition
Fan Zhang,Rui Li,Shuai Liu +2 more
TL;DR: This paper combines the background subtraction method with symmetric differential method to segment the motion human image, and then extracts the contour of motion human with improved GVF (gradient vector flow) Snake model.
Journal ArticleDOI

Journal ArticleDOI
Digital watermarking algorithm based on space-time coding
Fan Zhang,Xinhong Zhang,Rui Li +2 more
TL;DR: In this paper, the digital image watermarking system is extended from SISO to MIMO systems based on space-time coding and MIMo communication theory and the new watermarked algorithm is designed in the new framework of space- time coding andMIMO-based communication theory.
Book ChapterDOI
