| 摘 要： | 针对传统迭代反射投影方法得到的重建影像,其边缘部分存在锯齿效应和噪声信息,从而无法达到提升影像清晰度不足的问题。文中对初始重建影像,首先使用反锐化掩模方法提取其中的高频分量,并对高频信息进行分类,然后平滑掉其中的噪声信息,应用高频增强曲线对高频分量进行提升,保持高频分量的单调性。实验仿真结果表明,该方法可以消除噪声,小的边缘纹理细节得到增强,大轮廓没有过增强,可有效提升重建影像的清晰度。

| Abstract: | For the reconstructed image obtained by the traditional iterative back projection method,the edges of the reconstructed image have saw tooth effect and noise information,so that the image resolution can not be improved.First,the unsharp masking method is used to extract high frequency components of the initial image reconstruction, classify the high frequency information, then smooth the noise information.The application of high frequency enhancement curve is used on the high frequency component upgrade to maintain the monotonicity of high frequency components.The simulation result shows that this method can eliminate the noise,small edge texture details are enhanced,and the large contour is not enhanced,w hich can effectively enhance the clarity of the reconstructed image. |
