Abstract
We propose a new technique for retrieving color information. The color data taken by a digital camera is transferred to two-dimensional data on the color chart and displayed on a spatial light modulator. This modulation technique is combined with a retrieval technique using a joint transform correlator. The color data, e.g., photograph of a flower, are retrieved by this system, and the same color data (photograph) can be perfectly selected from the many reference data. This technique will open a new area of retrieval techniques for ambiguous images based on shape and color information.
