A Print-and-scan Resilient Digital Watermark for Card Authentication

Absbaef-In this paper, a secnm card authentication system based on digital watermarking is pmented. A sequence of identification characters e.g. owner’s ID number is inserted into the photograph, thus a linkage between the photograph and its owner c m he established. The print-and-scan process is successfdy uvemme by our transform d a e n t polarity based watermarking algorithm. The retrieval a...

Self-adaptive algorithm for segmenting skin regions

In this paper, we introduce a new self-adaptive algorithm for segmenting human skin regions in color images. Skin detection and segmentation is an active research topic, and many solutions have been proposed so far, especially concerning skin tone modeling in various color spaces. Such models are used for pixel-based classification, but its accuracy is limited due to high variance and low speci...

An algorithm for segmenting moving vehicles

An algorithm for region-based moving object segmentation is presented in this paper. The gray-scale image segmentation based on the Mean Shift Algorithm (MSA) is performed first to segment each frame of a sequence into connective homogeneous regions. A method applying spatio-temporal continuity constrains of the motion vector image is then carried out to detect moving pixels robustly. Finally, ...

An Online Algorithm for Segmenting Time Series

In recent years, there has been an explosion of interest in mining time series databases. As with most computer science problems, representation of the data is the key to efficient and effective solutions. One of the most commonly used representations is piecewise linear approximation. This representation has been used by various researchers to support clustering, classification, indexing and a...
