| 摘 要： | 医学图像边缘检测是医学图像处理和分析的关键步骤,它的清晰程度直接影响到医生诊断的速度以及准确性.传统边缘检测算子对噪声敏感,检测到的图像边缘效果不够理想,得到的图片边缘有可能模糊不清,为了克服传统边缘检测算子对噪声敏感的缺点,给出了一种改进的基于分数阶微分算法的医学图像边缘检测方法,实验结果表明:该方法不仅有效的提取了图像边缘特征,而且对噪声具有较好的抑制作用.是一种有效的医学图像边缘检测方法.

| Abstract: | Medical image edge detection is the key steps of medical image processing and analysis,the clarity of its direct impact on the speed of diagnosis,as well as accuracy.Traditional edge detection operators are noise-sensitive,edge detect effect is less than ideal,the edge of the picture may be blurred.In order to overcome the traditional edge detector sensitive to noise shortcomings,an improved approach is given based on fractional differential algorithm for medical image edge detection.Experimental results sh... |
