Create Watermarking_rgbimages.m

The following code implements our scheme for Digital Watermarking of rgb images making use of visual cryptography techniques. In this scheme the watermark is split into three shares such that the logical addition of all three gives back the watermark. The rgb image to be marked is split into three streams(RGB). Using the three watermark shares respectively for each image stream yields three verification matrices which are stored in a single rgb secret verification image.
