Abstract :
This paper presents results of an experiment performed on DCT block-based image watermarking algorithm. It also proposes and describes four factors that influence the performance of DCT block-based image watermarking algorithm. The experimental results show a great improvement on the performance of implementing the DCT block-based along with the proposed four factors.
