在 MATLAB Online 中打开

clc;
clear;
I = imread('../demo.jpg');
imshow(I)
grayImage = rgb2gray(I);
BW = im2bw(I);
imshow(BW)
hold on;
boundaries = bwboundaries(BW);[enter image description here][1]
fprintf('length values is = %i\n ',length(boundaries));
for k=14:14
   b = boundaries{k};
   fprintf('b values is = %i\n ',b);
   img = plot(b(:,2),b(:,1),'r','LineWidth',3);
end

Using regionprops(...,'BoundingBox'), will give the location, height, and width of the bounding box for each of the objects in the image.
