i cropped only the rectal part of mri images size 256 by 256 from pelvic mri images(size 512 by512) and train the unet model,after i want to display the segmented image by overlaying on the original pelvic image.here i want to put the small cropped and segmented image on original uncropped image that i didn't input to the model.
i tried the code below but its output is not what i want,i want the overlay to happen only at rectal part,
% Read the original image
originalImage = imread('20.jpg');
% Read the segmented test image
segmentedTestImage = imread('pixelLabel_20.png');
% % % Create a metal overlay effect using the imfuse function
overlayedImage = imfuse(originalImage, segmentedTestImage, 'blend', 'Scaling', 'joint');
% Overlay the binary mask on the original image
overlayedImage = labeloverlay(originalImage, segmentedTestImage );
% Display the overlayed image
imshow(overlayedImage);
the image is attached below.

See my attached demos about pasting an image onto another image. Adapt as needed.
