利用Matlab软件，具体实现对于给定图片的边缘提取、链接，同时计算计算图像中每个物体的边界长度、面积、矩，投影、近似圆形的离心率、紧致度和边界的傅立叶描述子。-Using Matlab software, the specific implementation for a given image edge extraction, linking, also calculated for each object in the calculation of the image boundary length, area, moments, projections, nearly circular eccentricity, compactness and boundaries of the Fourier descr iptors .
