Human behavior can be a direct reflection of their interest and purposes; therefore, we can take advantage of user behavior to predict their interest in the recommendation system. This paper analyzed the relationship between user behavior and interest in the recommender system of personalized video program, and summarized three potentially useful observations: selection, duration, repetition. Implicit...
How to extract the features quickly and correctly is the essential precondition for image identification and classification. As there existing large computation problems in the traditional feature extraction algorithms, this paper proposes a faster algorithm. Firstly, the image connected region is encoded by using the Vertex Chain Code to map as a closed area. Then a unified computational framework...
There has been a rapid increase in the need of accurate and reliable personal identification technologies in recent years. Among all the biometric techniques known, iris recognition is taken as one of the most promising methods, due to its low error rates without being invasive. Usually an iris recognition system consists of four steps: image acquisition, preprocessing, feature extraction and identification...
