基于形态学的口腔CT图像对比度增强方法研究
ON CONTRAST ENHANCEMENT METHOD OF ORAL CAVITY CT IMAGE BASED ON MORPHOLOGY
摘要
Abstract
Aiming at the problem of oral cavity CT image that its soft tissue part has low resolution and is unclear in details,we proposed a mathematical morphology-based image processing algorithm,which well avoids the defects of current common methods,including histogram equalisation,unsharp mask and wavelet threshold enhancement,generated in image processing such as the lost of details and the noise amplification,etc.By carrying out preprocessing of wavelet transform on the image,the algorithm enhances the expression of low frequency part of soft tissue information and reconstructs the image,and solves the noise amplification problem brought forward by information enhancement.At the same time,the morphological opening and closing cascade filter is introduced for feature information strengthening and further noise elimination and images smoothing.Experimental results prove the effectiveness of the algorithm,it is helpful for the clinic differentiation and diagnosis of the lesion of oral soft tissues.关键词
