内容記述 | In this paper, we propose a correlation based scheme of digital watermarking for images embedding the RDS (Random Dot Stereogram) in DCT (Discrete Cosine Transform) domain, and investigate the fundamental performance of the above scheme before and after attacks. First we show the definition of DCT, and describe some features of the RDS from the viewpoint of digital watermarking (i.e., information hiding) techniques. Next we explain basic procedures for the embedment and detection of our scheme. Finally we perform the computer experiments for some test images in order to examine the availability of our scheme. The experimental results show that our scheme using DCT provides better performance than the scheme using WHT (Walsh Hadamard Transform) in point of the BER (Bit Error Rate) property. | |||||
