For face recognition systems, impostors can obtain legal identity authentication by presenting the printed images, the downloaded images or candid videos to the sensor. In this paper, an enhanced face local binary feature (ELBP) of a face map is extracted as a classification feature to identify whether the face map is a real face or a fake face. Compared with the dynamic or static methods proposed...
Event extraction is a major task of Automatic Content Extraction (ACE) program. This paper focuses on the sub-task of event extraction, event argument identification, and proposes a novel method for Chinese event argument identification. The method involves two steps: (1) weighting features by the ReliefF algorithm for considering the particular contributions of different features on clustering analysis,...
This paper studies Regularized Discriminant Analysis (RDA) in the context of automatic airport recognition system for Forward-Looking infrared images (FLIR). When the within class covariance of training sample are sometimes singular, Linear and Quadratic discriminant analysis (LDA & QDA) does not necessarily give the best performance. Alternatives to the usual plug-in (maximum likelihood) estimates...
In this paper, we present a text-clustering algorithm of frequent term set-based clustering (FTSC), which uses frequent term sets for texts clustering. This algorithm can reduce the dimensionality of the text data efficiently, thus it can improve accurate rate and running speed of the clustering algorithm. The results of clustering texts by the FTSC algorithm cannot reflect the overlap of texts' classes...
