An image adaptive, wavelet-based watermarking of digital images (Q2475347)

This paper develops an interesting theory and experiments for image analysis using wavelet based water marking. The embedded watermark has a high level of robustness against geometric and image processing attacks and a low rate of false alarm. Using DWT on HSV color model, image statics features and image pre-processing steps with blocks of sub-division are the key steps in the deloved algorithm. The performed experiments are quite interesting.
