MATLAB: Get path to all files in a folder of images

% Directory
directory = 'C:\Datasets\nyu\train\';
img_dir = fullfile(directory, 'image_02');
depth_dir = fullfile(directory, 'depth');
image_rgb_info  = dir( fullfile(img_dir, '*.jpg'));
image_rgb_filenames = fullfile(img_dir, {image_rgb_info.name} );
image_depth_info = dir( fullfile(depth_dir, '*.png'));
image_depth_filenames = fullfile(depth_dir, {image_depth_info.name} );

MATLAB: How to take input image from user and Display

Prayag - assuming that the user actually chooses a file via

image=uigetfile([folder '\' ext]) ;

then image (this is poorly named as it conflicts with a built-in MATLAB function of the same name) will just be the name of the file and not the image itself (and so is an invalid input for imshow). Instead consider the following

[filename, path] = uigetfile(fullfile(folder,ext)) ;
imageData = imread(fullfile(path, filename));
imshow(imageData);
