主要讨论获得图片后如何提取其边界信息,首先利用图像灰度均匀化解决了对比度不清晰的问题,然后利用高斯滤波法对图片进行滤波去噪,进而利用Canny算法实现边缘检测提取边界,该方法与Matlab自带的求边界方法有明显的提高,为利用Matlab程序求图像分形维数提供了更精确的前提.

This paper mainly discusses how to get the border of an image. Firstly, use the method called gray symmetrization to increase the contrast ration. Secondly, process image by the method of gaus- sian filters. What is more, use more precise algorithm called Canny algorithm to get the border of an im- age. Based on this, we supply more precise presupposition for calculating the box dimension of the image with Matlab programming.
