A novel unconstrained correlation filter and its application in face recognition
- 信息技术－会议论文 
In this paper, a novel unconstrained correlation filter called Unconstrained Optimal Origin Tradeoff Filter (UOOTF) is presented and applied to face recognition. Compared with the conventional correlation filters in Class-dependence Feature Analysis (CFA), UOOTF increases the overall performance for unseen patterns by removing the hard constraints on the outputs during the filter design. Experimental results on the popular FERET, FRGC and CAS-PEAL R1 face databases show the effectiveness of the proposed unconstrained correlation filter. ? Springer-Verlag 2013.
