Spam is the use of electronic messaging systems to send unsolicited bulk messages indiscriminately. However, the popular spam filtering methods are encountering spammers' various disguise and confusion which seriously degrade the effect of spam filter. This paper proposes a collaborative spam filtering technique based on MIME fingerprints. By comparison(More)
Many problems in image processing and computer vision arise from shadows in a single color aerial image. This article presents a new algorithm by which shadows are extracted from a single color aerial image. Apart from using the ratio value of the hue over the intensity in some state-of-the-art algorithms, this article introduces another ratio map, which is(More)
Spam is unsolicited bulk email which is extremely annoying to the recipients and the ISPs. However, most of the traditional spam filtering methods commonly neglect the bulk character of spam. This paper proposes a model of cooperative anti-spam system based on multilayer agents. We compared our model to the state-of-the-art and found that our model achieved(More)

The technology of spam filtering is an effective method to discern spam and block their spread. The traditional anti-spam technologies have neglected spam's bulk feature, and some collaboration-based spam filtering technologies have individual technique standard. This paper proposes a spam filtering cloud platform based on sharing fingerprints. The cloud(More)
A new global stereo matching method is presented that focuses on the handling of disparity, discontinuity and occlusion. The Bayesian approach is utilized for dense stereo matching problem formulated as a maximum a posteriori Markov Random Field (MAP-MRF) problem. In order to improve stereo matching performance, edges are incorporated into the Bayesian(More)
