In this paper, we propose a new robust digital image blind watermark scheme that is used to protect color medical images. In this scheme, K-L transform is applied to an RGB medical image and the binary watermark is embedded into low frequency sub-band of DWT of the principal component of medical images. The embedding positions are chosen according to the human visual system (HVS). The embedding method is based on the relationship between center coefficients and the mean values of the nearest… CONTINUE READING
