select image from file in matlab

To select an image from a file in Matlab, you can use the imread function to read the image data from the file, and then display the image using the imshow function. Here's an example:

main.m
% Select the image file
[filename, pathname] = uigetfile({'*.jpg;*.jpeg;*.png;*.bmp', 'Image Files (*.jpg,*.jpeg,*.png,*.bmp)'},'Select an image file');

% Read the image data from the file
img = imread(fullfile(pathname, filename));

% Display the image
imshow(img);

9 lines

This code will display an open file dialog box that allows the user to select an image file. Once the user selects the file, the code reads the image data from the file and displays the image in a new figure window using the imshow function.
