摘要
单独采用中值滤波法与梯度法的其中一种 ,不能很好地改善CT图像质量。由于这两种方法具有互补效应 ,可用中值滤波法与梯度法对图像多次交替处理 ,使CT图像在去除噪声和保护图像边缘的同时使图像边缘得到增强。
In CT image processing, if the method of median filter or gradient are used apartly, the quality of image can′t be improved well. Because of the effect of commutative supplement of the two methods, they can be used mixed and alternately. The noise of CT image is not only eliminated, but also the information of image edge is reinforcel.
