Satoshi Ohga, Ryuji Hamabe · International Journal of Knowledge-based and Intelligent Engineering Systems · 2014
In this paper, we propose a new digital watermarking method based on fractal image coding using DWT and HVS. The method decomposes an original image into subbands LL1 and LL2 using DWT. In fractal image coding, LL1 and LL2 are used for the range bloc
