这是计算图像中对象数量的 MATLAB 代码步骤之一。
B = bwboundaries(img2);
imshow(img2)
text(10,10,strcat('\color{green}Objects Found:',num2str(length(B))))
hold on
虽然对代码给出的解释是
> This step finds the boundaries of each object that it finds and stores
> it in B. The text function prints the number of objects that are found
> by bwboundaries.
但我无法理解第 3 步。谁能简要解释每一行的代码。谢谢。
