一个简单的傅立叶带亮度描绘子提取图像的形状特征程序-A simple Fourier descr iptor with the brightness of the image shape feature extraction procedures

The objective is to illustrate the coordinated sampling of a geometrical shape such as an eclipse is used in this case. For illustrative purposes the gridded plot is sampled by detection of line beam intersections of the edge and in-bound regions o
