Basically I had two images which I overlayed using control point registration; the final part of the code is :
[registered2, xdata, ydata] = imtransform(unregistered1, tform,...
'FillValues', 255);
figure; imshow(registered2, 'XData', xdata, 'YData', ydata)
hold on
imshow(unregistered);
ylim = get(gca, 'YLim');
set(gca, 'YLim', [0.5 ylim(2)])
set(gca,'XLim',[0 7000])
I want to further use this final image (dont need to save it). Like;
cpselect(final_image_from_above, new_unregistered_image)
However, i have tried getframe(), saveas(), etc. But the problem with that was the quality of the image gets very bad.
Thanks,

Take a look at imfuse in the image processing toolbox. If you use the 'blend' display option, the resulting image output will be a 50/50 alpha blended version of the two input images.

I thought you said "dont need to save it" - anyway, to save, have you tried imwrite()?

Yes I dont have to save it if I can re-use the final image without saving it.
