Abstract

This paper uses adaptive histogram equalization to enhance the contrast of X-ray chest image. Several methods are presented to eliminate the noise caused by the enhancement. The mainly used methods are frame averaging, bandstop zero-phase filtering based on 2D FFT. The cause of noise is also analyzed.
