MATLAB Ellipse Shaped Cropping for Faces and Other Applications

% This is a simple MATLAB program where the user selects an image and is able to manually crop an %image in an ellipse like shape. %https:/youtu.be/igPtFauGoA8 % youtube video using the code [FileName,PathName] = uigetfile({'*.jpg;*.tif;*.png;*.gif','All Image Files'},'Please Select an Image'); image = imread([PathName FileName]); imshow(image) %needed to use imellipse user_defined_ellipse = imellipse(gca, []); % creates user defined ellipse object. wait(user_defined_ellipse);% You need to click twice to continue. MASK = double(user_defined_ellipse.createMask()); new_image_name = [PathName 'Cropped_Image_' FileName]; new_image_name = new_image_name(1:strfind(new_image_name,'.')-1); %removing the .jpg, .tiff, etc new_image_name = [new_image_name '.png']; % making the image .png so it can be transparent imwrite(image, new_image_name,'png','Alpha',MASK); % everything not in the MASK region is %transparent msg = msgbox(['The image was written to ' new_image_name],'New Image Path'); waitfor(msg); % if you have any questions, comments, or concerns, please email me at mgalarny@gmail.com
