How do I run all images in a folder through an image processing code?

I have written code to process an image in a certain way. I want to be able to add a bunch of similar images into a folder and possibly create a loop that processes each image through the code. Ideas or hints would be greatly appreciated.

You can find simple snippets in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

Or you can find a nice GUI framework here: http://www.mathworks.com/matlabcentral/fileexchange/24224

A simple GUI based approach is to use Image batch Processor. Start it using

imageBatchProcessor

You can specify the input dataset containing multiple images. You can specify the function you want to apply and also use parallel processing directly from the app to speed up the processing. It will also give the option to save all the processed file in a folder or the workspace.

For doing it programmatically, refer to this link. The general idea is to loop through all files as shown here

files = dir('*.jpg');  % specigy the extension of your image file
for i = 1:numel(files);
  filename = files(i).name;
  image = imread(filename);
  % apply processing to the loaded image
  % save the image to an array or back to the folder using 
end

kindly use Image Batch Processor app, already installed in matlab. Just import data from your folder, define a function, and process it.
