Hi everyone, As some of you are aware I have been looking at stego, in particular trying to calculate the maximum feasible message to insert in a given image. I have determined some techniques that help predict this ratio. In the process of testing them I got side-tracked into converting images to other format (RGB > HSV in this case). Since these are linear but not equaly scaled there is some range alteration in the conversion process. It appears that if a RGB image is holding a image it converts to HSV differently and is thus easy to test for. I am in need of some additional data and basiclly clueless where to find it. The data falls into one of the following ways: > source of images in both HSV and RGB format > pd or shareware software that will convert mathematicaly > access to a video color registration set to generate the above database Any help in locating any one of these would be greatly appreciated. Have a Merry Christmas! Ravage Black Leather Monster
