Reading images from a file in MATLAB

Question

I have bmp images in the image folder on my computer. I called it from 1.bmpto 100.bmp.

And I want to read these images as follows:

for i=1:100
    s='C:\images'+i+'.bmp';
    A=imread(s);
end

But Matlab made a mistake. How to implement this?

Answer 1

You can use the function sprintf

s = sprintf('c:\images%d.bmp', i);
A = imread(s);

You can read more about string handling in matlab here.

Answer 2

Create sas follows:

s = ['C:\images\' int2str(i) '.bmp'];

In addition, your loop will simply overwrite A, so you will have to make it a cell array in order to save all 100 images. Do this outside your loop:

A = cell(1,100);

:

A{i} = imread(s);

Answer 3

. C:\images1.bmp. , , , , ypnos.

Answer 4

imgfiles=dir('c:\images\*.*');
for k=1:length(imgfiles)
  ...
end 

Answer 5

matlab .

files=dir('*.bmp') for k=1:numel(files) I=imread(files(k).name); end

.
