摘要
针对x射线康普顿背散射安检图像在噪声、背景均匀性和对比度等方面存在的问题，根据辐射成像系统自身的特点设计了一种混合滤波器，用于改善图像质量。经过图像滤波后，在监视器终端获得了层次清晰、轮廓分明、背景均匀的x光背散射图像。
Considering to the radiation image system charactertics and the existing problems of X-ray Compton back- scattering image, such as noise, background uniformity and contrast, a new hybrid filter is designed which is used to improve the image quality. After fihered, the X-ray back-scattering image with clear levels, distinct outline, uniform background will be displayed on the screen.
