Abstract: Methods and apparatus for spectrally-encoding plural source images and for providing the spectrally-encoded plural source images in a composite image, for rendering the composite image in a physical form, or for recovering at least one of the encoded source images from the rendered composite image such that the recovered source image is made distinguishable. The composite image is generated using an image-dependent dynamic range determination so as to provide a maximum usable contrast in a recovered source image.

Abstract: Methods and apparatus for spectrally-encoding plural source images and for providing, the spectrally-encoded plural source images in a composite image, for rendering the composite image in a physical form, or for recovering at least one of the encoded source images from the rendered composite image such that the recovered source image is made distinguishable. A noise component is introduced in the encoding of the plurality of source images so as to mask at least one of the source images during spectral demultiplexing.

Abstract: Methods and apparatus for spectrally-encoding plural source images and for providing the spectrally-encoded plural source images in a composite image, for rendering the composite image in a physical form, or for recovering at least one of the encoded source images from the rendered composite image such that the recovered source image is made distinguishable. Source image confusion in a rendered composite image is controlled by application of a multi-illuminant gray component replacement (GCR) technique to the darkness common to the different colorants under the multiple illuminants.
