The data structure of a RGB color image is utilized by the information embedding based on KL (Karhunen Loeve) transformation of color space.In three components obtained by the transformation, embedding using the smallest component of the eigen value is performed.Moreover, the embedded watermark is unevenly distributed to the part in image space.The previous work [12] showed that an embedding image that does not spoil the quality of a color image was created using this character.Furthermore, by this method, a component suitable for embedding increases with the rise of the number of dimensions of component data obtained by transformation of color space.In this paper, we propose embedding a different watermark using two or more components.An experiment shows an embedding result.Moreover, the analysis result based on the eigen value of an original color image is also shown. |
