我有这段代码，我需要输入一个图像并输出一个带有三角形，正方形，圆形，星形或矩形的字符串。对完成这个项目有什么帮助吗？
“仅黑白图像
clear all close all im=imread('circulo_fr.jpg'); img=rgb2gray(im); BW=im2bw(img); stats=regionprops(BW,'Perimeter','Area','Centroid','BoundingBox'); figure,imshow(BW); hold on for k=1:length(stats) thisboundingbox=stats(k).BoundingBox; if stats(k).Area>10000 retangulo('Position',[thisboundingbox(1), thisboundingbox(2), thisboundingbox(3), thisboundingbox(4)], 'EdgeColor','r','LineWidth',2); else retangulo('Position',[thisboundingbox(1), thisboundingbox(2), thisboundingbox(3), thisboundingbox(4)], 'EdgeColor','b','LineWidth',2); end if stats(k).Perimeter^2/stats(k).Area > 18 text(stats(k).Centroid(1),stats(k).Centroid(2),'Triangulo','Color','r'); elseif stats(k).Perimeter^2/stats(k).Area < 14.3 text(stats(k).Centroid(1),stats(k).Centroid(2),'Circulo','Color','g'); else text(stats(k).Centroid(1),stats(k).Centroid(2),'Quadrado','Color','b'); end
