Recent Advances in White-Light Image Processing

Abstract

Publisher Summary The basic principle of a white-light image processor is very suitable for color image processing. This chapter describes a technique that permits certain image processing operations to be carried out by a spectrally broadband light source––white light. This method is capable of performing image processing that obeys the concept of coherent light. The proposed white-light image processing system is linear in complex amplitude. The white-light processor is operating in a partially coherent mode so the image can be processed in complex amplitude. The coherence requirement for white-light image processing is analyzed through the partial coherence theory. Some of the recent advances in white-light image processing—such as the advantage of capacity, color, simplicity, and cost—are also described in the chapter. The color image deblurring, color image subtraction, color image retrieval, and pseudocolor encoding can be easily carried out by the proposed white-light processing technique. The white-light image processing operations can be evaluated from the stand point of conventional linear systems.
