摘要：

In this paper, we investigate the problem of choosing the best domain for embedding watermarks in digital still images. During this paper, twelve watermarking techniques were implemented and evaluated. Four techniques were selected to represent different approaches of embedding data in spatial domain, three approaches using discrete cosine transform (DCT) domain, two approaches using discrete wavelet transform domain (DWT) domain, and two combined DWT-DCT techniques. The algorithms were chosen to represent a range of computational complexities and implementation structures. The performance of the selected algorithms was evaluated with respect to many perceptibility parameters.
