In this paper, a new face detection approach based on skin color segmentation is presented. First, the color image is converted into YCgCrcolor space from RGB, because the performance of clustering is excellent in YCgCr color space. We get the segmented image by using the algorithm of support vector machine in YCgCr color space. Finally, we offer a face verification algorithm according to the geometric...
Most existing corpus based relation extraction techniques focus on predefined relations. In this paper, a clustering based method is presented for domain relevant relation extraction including both relation type discovery and relation instance extraction. Given two raw corpora, one in the general domain, one in an application domain, domain specific verbs connecting different instances are extracted...
