1．任意选取一个灰度图像和彩色图像，对算法中若干关键语句中的参数进行调整，得出不同的实验结果，并对这些结果进行分析。

2．根据自己所学知识，提出自己的轮廓线提取方法，与简单阈值法进行比较分析。

3．练习matlab自带算子的检测结果。

-1. Arbitrarily select a gray-scale images and color images, several key statements on the algorithm to adjust the parameters, results in different experimental results, and these results were analyzed. 2. Learned based on their knowledge, put forward its own contour extraction method, with a simple threshold method for comparative analysis. 3. Matlab built-operator practice test results.
