基于HVS和小波多分辨率的X射线图像质量评价

摘要

针对X射线图像质量评价问题，研究了HVS（人眼视觉系统）及小波多分辨率，在此基础上提出一种基于两者相似性的图像质量评价方法。通过对不同管电压作用下产生的X射线图像感兴趣区域进行评价处理，将评价结果与主观评价法、传统客观图像质量评价方法作对比，结果显示，所提出的图像质量评价方法，其结果更接近人眼视觉评价结果。%Aiming at the problem of X-ray image quality evaluation, this paper studies the HVS (human visual system) and wavelet multi-resolution, and proposes an image quality evaluation method based on the similarity between two of them. Evaluating the interest region of the images generated by different X-ray tube voltages, compared the results with those of the subjective evaluation method and the traditional objective image quality evaluation method, results show that with the image quality evaluation method proposed in this paper, the result is closer to that of human visual evaluation.
