Histogram-based segmentation in a perceptually uniform color space
—In this work, we present a segmentation algorithm for color images that uses the watershed algorithm to segment either the twodimensional (2-D) or the three-dimensional (3-D) co...

Redundant-wavelet watermarking with pixel-wise masking
An algorithm is presented which implements image watermarking in the domain of an overcomplete, or redundant, wavelet transform. This algorithm expands on a previous method which ...
