A Study Transform Coding of Medical Image Using Adaptive Quantization Method

적응 양자화를 위한 의료 영상 정보의 변환 부호화에 관한 연구

In this study, medical images, which are X-ray image and CT image, are compressed by the adam live coding technique. The medical images may be treated as special ones, because they are different from general images in many respects. The statistical characteristics that medical images only have in transform domain are analyzed, and then the improved quantization method is proposed for medical images. For chest X-ray image and CT head image, the better results are obtained by the improved adaptive coding technique.
