利用MATLAB展示风玫瑰图,进行气象分析，统计分析，以及风资源分析(plot windrose pictures by matlab)

harris算子迹实验，以harris为角点检测算子，计算自相关矩阵M的迹图像。(the harris operator trace experiment, harris corner detection operator, calculated from the trace of the matrix M image.)

进行图像的角点提取，方法是先通过Harris方法选初始点，然后对初始点进行Forstner算法进行筛选，最后得到图像角点。(The image of the corner detection, the method is to first select the initial point through the Harris method, and then point Forstner initial screening algorithm, the resulting image corner.)
