I'm not sure I believe you that imresize() does not work. What do you notice when you run this code:
fontSize = 22;
rgbImage = uint8(randi(255, [776, 608, 3]));
subplot(1, 2, 1);
imshow(rgbImage);
title('Original Size Image', 'FontSize', fontSize);
axis on;
rgbImage2 = imresize(rgbImage, [645, 463]);
subplot(1, 2, 2);
imshow(rgbImage2);
title('Re-sized Image', 'FontSize', fontSize);
axis on;
% Enlarge figure to full screen.
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);

That looks more involved that I can solve in a few minutes and post here. So, good luck. You might try feature identification methods like MSER (http://en.wikipedia.org/wiki/Maximally_stable_extremal_regions), SURF, corner(), etc. SURF and MSER are in the Computer Vision Toolbox. corner() is in the Image Processing Toolbox.
