The local fuzzy fractal dimension (LFFD) is proposed to extract local fractal feature of medical images. The definition of LFFD is an extension of the pixel-covering method by incorporating the fuzzy set. Multi-feature edge detection is implemented with the LFFD and the Sobel operator. The LFFD can also serve as a characteristic of motion in medical image sequences. The experimental results show that the LFFD is an important feature of edge areas in medical images and can provide information for segmentation of echocardiogram image sequences.
提出局部模糊分形维数(LFFD)来提取医学图像的局部分形特征。LFFD的定义是通过纳入模糊集对像素覆盖法的扩展。利用LFFD和Sobel算子实现多特征边缘检测。LFFD还可作为医学图像序列中运动的一个特征。实验结果表明,LFFD是医学图像边缘区域的一个重要特征,可为超声心动图图像序列的分割提供信息。
