Spectral Color Imaging
In fully understanding the color and its digital management, a three dimensional color representation (e.g. RGB) is not enough. The color should be represented by a n-dimensional color spectrum. Nowadays many ...

Digital Watermarking of Spectral Images with Three-Dimensional Wavelet Transform
We propose a watermarking method for spectral images. The watermark is embedded in the three-dimensional wavelet domain of the image. Before embedding, the gray-scale watermark is transformed with the two-dime...
