A comparison of DFT and DWT based similarity search in time-series databases
TL;DR: The feasibility of replacing DFT by DWT is explored with a comprehensive analysis of the DFT and DWT as matching functions in time-series databases and the results show that although the DWT based technique has several advantages, it does not reduce relativ e matching error and does not increase query precision in similarity searc h as suggested by previous works.

TL;DR: With these study results, it is believed the Web users would like to build and organize a larger collection of bookmarks for future references than they can reasonably maintain now.
Proceedings ArticleDOI
Using visual features for anti-spam filtering
TL;DR: A novel anti-spam system which utilizes visual clues, in addition to text information in the email body, to determine whether a message is spam, using one-class support vector machines (SVM) as the underlying base classifier for anti- Spam filtering.
Proceedings ArticleDOI
Adaptive learning of an accurate skin-color model
TL;DR: An adaptive skin-detection method, which allows modeling true skin-color distribution with significantly higher accuracy and flexibility than other methods attain, and can be applied to both still images and video applications.
Journal ArticleDOI
Discovery of a perceptual distance function for measuring image similarity
TL;DR: Through mining a large set of visual data, a team has discovered a perceptual distance function called DPF, which performs significantly better than Minkowski-type distance functions in image retrieval and in video shot-transition detection using the authors' image features.
