摘　　要：目的对手腕骨数字图像的质量进行评价。方法应用模糊数学中的三角模算子,定义数字图像的模糊度,用模糊度算法计算手腕骨数字图像的模糊程度。结果模糊度指标符合人眼的视觉感受,图像模糊程度和模糊度之间存在对应关系。结论模糊度适用于评价图像品质。Objective To evaluate the quality of digital X-ray pictures of wrist bone. Methods A definition of the fuzzy degree of the digital picture was put forward by triangular norm operator, and the fuzzy degree of the wrist bone picture was quantitative calculated. Results The definition of the fuzzy degree was accordant with human visual perception. There was the correlation between the blurred image and the fuzzy degree of the wrist bone image. Conclusion The fuzzy degree of image can be used to assess the image quality.
