Loading multiple images in MATLAB

Question

Here is the desired workflow:

• I want to load 100 images into MATLAB workspace
• Run a bunch of my code on the images
• Save my output (the output

Answer 1

Assuming that your images are named in a sequential way, you could do this:

N = 100
IMAGES = cell(1,N);
FNAMEFMT = 'image_%d.png';

% Load images
for i=1:N
  IMAGES{i} = imread(sprintf(FNAMEFMT, i));
end

% Run code
RESULT = cell(1,N);

for i=1:N
  RESULT{i} = someImageProcessingFunction(IMAGES{i});
end

The cell array RESULT then contains the output for each image.

Be aware that depending on the size of your images, prefetching the images might make you run out of memory.
