A considerable amount of research work has been done for facial expression recognition using local or global feature extraction methods. Weber Local Descriptor (WLD), a simple and robust local image descriptor, is recently developed for local feature extraction. In facial expression recognition, the information contained in the local is important for the recognition result. The Histograms of Oriented...
Based on the researches of LSB (least significant bit, i.e. the last bit of a binary pixel value) matching steganographic method and the steganalytic method which aims at histograms of cover images, this paper proposes a new LSB matching steganographic method. A steganographic information table is defined to record the changes which are introduced by the embedded secrete bits. According to the table,...
We propose a simple approach to fast extract the main text content from Web pages, especially online news pages. Most existing approaches need to construct the DOM tree structure from the HTML source of the Web page first, and then, extract the important content by pruning/merge the DOM branches/sub-trees. Such DOM tree processing tasks are very time-consuming. Our solution processes the HTML source...
