Robust Watermarks for color JPEG in Java A Java implementation of an algorithm using DCT to embed binary data or text messages into a color pictures. It resist some cropping, scaling or JPEG compression. The implementation also uses Reed-Solomon error correction to extract the exact bits, even in case of watermark destruction. Watermarks here is an example watermark: water1.raw Here you see the bits 8x8 pixel wide that form a 128x128 pixel watermark that will be embedded into an image. water2.raw This is a watermark that was extracted from an image. It"s not that crisp as
