Combining double random phase encoding for color image watermarking in quaternion gyrator domain

Quaternion representation of color image has attracted great attention due to its capability to treat holistically the three color channels. In a more general way, it has successfully been used in multi-channel signal processing applications over the past few decades. In this study, a joint encrypti...
