| 摘 要： | 通过实验分析了X射线对CCD的影响以及射线噪声的特点 ,并针对这种噪声的性质提出了菱形均值滤波器。经过计算机仿真滤波实验和实际应用 ,与递归与非递归中值滤波器作了对比 ,表明该滤波器不但能有效滤除脉冲噪声 ,而且能够较好地保持图像边缘和细节。

| Abstract: | Based on the experiments, the influence of X-ray on CCD is analyzed and the properties of the noise from X-ray radiation are obtained. A rhombus-average filter is presented for removing the kind of noise and compared with the recursive and non-recursive median filter through the simulations and actual application. It is shown that the filter presented has the ability of effective removing impulse noise and better protection for edges and details. |
