Mixed noise removal for color images using quaternion representation被引量:2
《Journal of Southeast University(English Edition)》2015年第3期347-352,共6页王定成 田宇航 陈北京 舒华忠 
The National Natural Science Foundation of China(No.61572258,61173141,61271312,61232016,61272421);the Natural Science Foundation of Jiangsu Province(No.BK2012858,BK20151530);the Natural Science Foundation of the Jiangsu Higher Education Institutions of China(No.13KJB520015);Open Fund of Jiangsu Engineering Center of Network Monitoring(No.KJR1404)
In order to effectively restore color noisy images with the mixture of Gaussian noise and impulse noise,a new algorithm is proposed using the quaternion-based holistic processing idea for color images.First,a color im...

Action recognition using a hierarchy of feature groups
《Journal of Southeast University(English Edition)》2015年第3期327-332,共6页周同驰 程旭 李拟珺 徐勤军 周琳 吴镇扬 
The National Natural Science Foundation of China(No.60971098,61201345)
To improve the recognition performance of video human actions,an approach that models the video actions in a hierarchical way is proposed. This hierarchical model summarizes the action contents with different spatio-t...

Enhanced hyperspectral imagery representation via diffusion geometric coordinates
《Journal of Southeast University(English Edition)》2009年第3期351-355,共5页何军 王庆 李滋刚 
The National Key Technologies R & D Program during the 11th Five-Year Plan Period (No.2006BAB15B01)
The concise and informative representation of hyperspectral imagery is achieved via the introduced diffusion geometric coordinates derived from nonlinear dimension reduction maps - diffusion maps. The huge-volume high...
