Re-using an overlayed image?

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.

Use fuse where?? The question was how to use/save the final image after 'hold on'. my final image is two not fully overlayed images. Now i need to save it so i can use it again, or just use it again without saving it! thanks,

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.
