摘要
在传统中值滤波的基础上，根据扫描进入计算机后人体关节CT图象的特点，提出一种在消除孤立噪声、保护边缘的同时使图象边缘得到增强的改进中值滤波法。这种方法可以使CT图象处理具有高的准确性、实时性。
On the basis of the conventional meidan filtering, An novel method of the improved median filtering was provided according to the characteristic of the CT image of human body joint through the computer scanning. Compared with conventional method of median filtering, the improved median filtering not only eliminated validly the stochastic noise of the human body joint, but also reinforced the information of the image contour. This method could be made the processing effect of CT image possess the higher accuracyand relativity.
