摘　　要：针对当前激光X光医学图像去噪后图像细节模糊以及图像去噪过程复杂,去噪速度慢问题,提出中值非局部平均算法的激光X光医学图像去噪系统,首先设计激光X光医学图像去噪后系统总体框架,然后通过分析非局部平均方法的实现过程,采用中值非局部平均算法实现激光X光医学图像去噪,保证去噪后图像细节的清晰度,并通过解剖端纳入不受限分割的方法降低方法的计算复杂度,实验结果表明,本文系统能够有效去除激光X光医学图像中噪声,去噪后图像细节较清晰,图像质量较高,且去噪速度较快。In view of the current X laser light medical image denoising and image blurring,image denoising process is complex,denoising is slow,so denoising system of laser light X medical image of median non local average algorithm is designed for laser light X medical image denoising system framework,and then through the implementation process analysis the local average method,the non local average algorithm of median X laser light medical image denoising,the definition of image denoising details can be ensured,and the calculation method is not limited in the end anatomical segmentation method to reduce the complexity,the experimental results show that this system can effectively remove the noise of laser light to X medical image. The denoised image remains clear details,high image quality,and fast denoising speed.
