Comparison of Digital Water Marking methods
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 9
Abstract
In Digital watermarking, image or video is embedded information data within an insensible form for human visual system but in a way that protects from attacks such as common image processing techniques. Spatial domain(Least significant bit(LSB)) and transform domain (Discrete Cosine Transform(DCT) and Discrete Wavelet Transform(DWT)) methods are used. DWT is best method because of using embedded zero tree wavelet image compression scheme and high frequency sub bands.
