基于多分辨率分析理论的口腔CT图像的增强

Enhancement of CT's image of nonnasality based on the multiresolution ratios analysis

针对牙齿CT影像经常出现的正常组织和病态组织之间对比度不清的问题,提出了基于小波变换的图像多分辨率梯度信息的医学图像增强算法,算法原理简单、实用,较好地解决了牙齿图像对比度增强的问题。

Aimed at the unclear contrast ratio problem between normal organization and morbid organization of the CT's image of nonnasality,presents a enhanced algorithm of medical image multiresolution ratio gradient information of DWT .It is not only simple,practical,but a better settlement on the contrast ratio enhancement of nonnasality image.
