Abstract
Negatives of variable digital holographic images may be generated based on desired images and generic optical matrices. An original image may be obtained. A geometry associated with a generic optical matrix may be obtained. The generic optical matrix may have pixels corresponding to color and sub-pixels corresponding to non-color effects. The geometry may indicate locations and colors of pixels in the generic optical matrix, and locations and non-color effects of sub-pixels within the pixels. Color separation may be performed on an original image to provide two or more separations. The separations may be indexed to the geometry associated with the generic optical matrix to provide indexed separations. The indexed separations may be merged to provide a negative of the original image.
