Conference on Wavelets and Sparsity XIV
作者: Li, Shidong Mi, Tiebin Liu, Yulong San Francisco State Univ Dept Math San Francisco CA 94132 USA Renmin Univ China Sch Informat Beijing Peoples R China
A notion of sparse dual frames for a given non-exact frame is introduced. The sparse dual frame is motivated in a study of compressed sensing problems where signal are sparse with respect to a redundant and coherent d... 详细信息

JOURNAL OF ELECTRONIC IMAGING 2010年 第1期19卷 013009-013009-8页
作者: Zhang, Yi Yang, Jie Liu, Kun Shanghai Jiao Tong Univ Inst Image Proc & Pattern Recognit Shanghai 200240 Peoples R China
We redefine the unusual event detection problem from a different point of view. Several fundamental event features are investigated and adopted. These features are redescribed in a uniform model. Thus, using this mode... 详细信息

Conference on Signal Processing, Sensor Fusion, and Target Recognition XIX
作者: Mahler, Ronald El-Fallah, Adel Lockheed Martin MS2 Eagan MN 55121 USA Sci Syst Co Inc Huntsville AL USA
The conventional PHD and CPHD filters presume that the probability p(D)(x) that a measurement will be collected from a target with state-vector x (the state-dependent probability of detection) is known a priori. Howev... 详细信息
