摘要
普通的阈值选取方法只注重图像的灰度信息,而很少考虑图像的空间信息。分形维数能很好地反映一幅图像的空间信息,在图像的处理与分析中得到了很好的应用。提出了一种基于分形维数的图像阈值选取方法,实验证明对于灰度图像的阈值选取具有很好的实用效果。
The common methods of threshold selection only use the gray information of images, not making good use of the space information. Fractal dimension is a good index of space information of images, widely used in digital image processing and analysis. A method of threshold selection based on fractal dimension was proposed. Experiments show that it is effective to the threshold selection.
