Abstract

An image enhancement method-the real-time image cosine transformation is presented. The photo intensity signal from an X-rayogram which corresponds to a single period of the cosine function is coded through a cosine transformation processor(CTP)1, and then decoded and made reappearance of the Image by means of a television mornitoring system. The image coding and the decoding are discussed. The step wave processing by the CTP 18 shown, and the experimental results of X-rayograms processing in the early stage of pathological changes are given.
