Method for cross-device color calibration and enhancement using explicit constraints.
摘要
<p>This invention provides a method for transforming an input color space to an output color space where each of a plurality of specified colors and/or color regions are constrained to be transformed by any one of a plurality of explicitly specified color calibration or color enhancement strategies. The method involves a two step process: 1) constraints are applied to some subset of the points in the input color space explicitly specifying the transform into the output color space; 2) the remainder of the points are then transformed by a mapping strategy which preserves color continuity. The mapping strategy used in the preferred embodiment is based on a computer graphics geometric morphing technique. In the preferred embodiment, multi-dimensional look-up tables are used to implement the color transformation. <IMAGE></p>
