摘要： Briefly, in accordance with one embodiment of the invention, a method of using hue to interpolate color pixel signals includes the following. For a particular pixel location in a subsampled color image, differences in hue are compared for two mutually orthogonal directions across the particular pixel location. A color signal value for that particular pixel location for a color plane other than the color plane of the pixel signal value in the subsampled color image of that location is computed. The computation includes relatively weighing the differences in hue values, the relative weights depending, at least in part, on the difference in hue value in one direction relative to the other.

摘要： A method of encoding a watermark into a digital image. The method includes partitioning an original image into blocks and then determining a variance value of each block. The blocks are then arranged according to the variance values. A number of selected blocks are identified, where the number depends upon the size of the watermark. The blocks selected are then arranged by their location. Data from the watermark is used to replace bits in a representation of each of the selected blocks with data from the watermark. A method of decoding is also discussed.
