摘要
针对传统空间滤波器在对X射线图像进行平滑滤波时造成图像边缘模糊现象的问题,提出一种采用双边滤波器对X射线图像进行平滑滤波的一种方法。与传统图像滤波方法不同,双边滤波器不但能对图像进行滤波,而且能保护边缘信息,而传统空间滤波器对图像滤波时会造成图像边缘模糊。双边滤波器是在空间滤波器的基础之上采取动态改变滤波器的方法来对图像进行滤波。最后通过采用不同滤波器对噪声图片进行平滑滤波,验证双边滤波器的平滑滤波效果。
Aiming at the question that traditional filters bring about edge blur in images, a filtering method is presented with bilateral filter for applications in X-ray image processing. Being different from traditional image filtering methods, which bring about edge blur in images, bilateral filters are able not only to filtrate the images＇ noise, but also to protect the information of edges. At the base of special filters, bilateral filters take measures that change the filter dynamically to filtrate the noise. At last, using different filtering methods that filtrate images＇ noise proves the filtering effects using bilateral filters.
