Hi, I'm working with image processing and I can't find a code where, whenever I run the script, I can browse and choose the image on the computer, instead of changing my code.

I = imread('foto1.jpg');
res = quantSoja(I);

quantSoja() is a function I created for processing.

I want to replace "imread" with another command so that I can browse the computer.

在 MATLAB Online 中打开

Try this:

% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = pwd;  % or 'C:\wherever';
if ~isfolder(startingFolder)
    % If that folder doesn't exist, just start in the current folder.
    startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.*'); % or *.jpg if you want to limit files shown to JPG files.
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file');
if baseFileName == 0
    % User clicked the Cancel button.
    return;
end
fullFileName = fullfile(folder, baseFileName)
rgbImage = imread(fullFileName);
imshow(rgbImage);
