| 摘 要： | 基于X射线影像增强器的视觉系统所成图像的缺点是动态范围小,对比度不够高。为此,提出一种新的X射线图像增强算法。首先在高低两个不同射线管电压下分别获取两幅图像,利用离散小波变换对其进行多分辨率图像融合,以扩展X射线图像动态范围,之后再利用双平台直方图均衡算法对融合图像进行增强。实验结果显示,射线图像得到有效增强。 |
| 关 键 词： | X射线图像 图像增强 图像融合 双平台直方图均衡化 |

| Abstract: | Since the images produced by the vision system based on X-ray image intensifier often have limitations such as narrow dynamic range,and low contrast,a new X-ray image enhancement algorithm is raised here.Two X-ray images taken at different X-ray tube voltages and currents are fused by digital wavelet transform to expand the dynamic range of the X-ray images,and then adopts the dual-platform histogram equalization algorithm to enhance the fused image.The experimental results show that the X-ray images are en... |
