Abstract†

• Since most of the current digital cameras, images, and displays are formatted in an RGB color space, it is difficult to introduce multispectral applications into RGB imaging systems. Therefore, we propose to embed spectral data into RGB image. The obtained RGB image can be used as an usual RGB image for sharing/viewing, meanwhile, multispectral image can be reconstructed by extracting spectral data.

Multispectral information embedding into RGB image based on watermarking†

• The lower bit planes of RGB images are not significant information for human perception. We achieved a balanced performance in both RGB and spectral data by embedding the estimation error of multispectral data calculated from RGB into the lower bit planes of RGB image. Additionally, the proposed method has a compression tolerance.
