Abstract
Methods and systems for color conversion used in image-processing. In one approach, a caching strategy can be employed rather than a direct computation or a precomputed table. To improve the hit frequency and reduce storage requirements, a hash calculation in addition to comparison operations can be processed as a 'near match' rather than an exact match. In another approach, 'fuzzy match' caching can be implemented to reach the proper vicinity in the n-dimensional space, and then interpolation (or extrapolation) can refine the result.
