How I use bounding box for multiple objects?

I write a code for bounding box, but this code work just one object. How I use bounding box a lot objects.(I want to write algorithm, I do not use any command or library.)

The code is,

clc,

clear,

im1=imread('binary_image');

im1_binary=imbinarize(rgb2gray(im1));

bottom=-1;

right=-1;

top=439;

left=470;

for row=1:439

for column=1:470

if (im1_binary(row,column)==1)

if(row>botton) botton=row;

end

if(column>right) right=column;

end

if(row<top) botton=row;

end

if(column<left) left=column;

end

end

end

end

Try to use "Image Labler app". It will solve your issue. you can choose your multiple ROI from an image and my exporting it will return you multiple boundry boxes for multiple objects.

Thanks for your answer,

but I do not want to use any apps or any libraries. I want to use one algorithm. This algorithm do to seperate white objects in background(background of course black). Thanks for your helps.
