Multiscale Display Processing of Radiographic Images Acquired with a Protoype Flat Panel Detector

Abstract

This paper study softcopy display algorithms of digital radiographic images acquired using a prototype flat panel detector. The processing is manipulated in two steps. Firstly, a look up table is applied to map the gray value of original image into proper visual scope. Then, the mapped image is decomposed into a serial subband images with a multiscale pyramid structure. The contrast of subband images are enhanced by using nolinear functions. Both performance and computational simplicity make our algorithms attractive.
