You can change the image matrix size with imresize(). This does not change the actual real world spatial resolution (like how well you can resolve to points close together in the scene), just the number of pixels. To increase the resolution you need to use a spatial filter, like deconvlucy() or wiener2() which require you to supply a point spread function and a noise spectrum.

Or you can look to section 18.4.3 here: VisionBib

You could look into techniques for super resolution. This is an entire field of research that uses multiple low resolution images to create high resolution images.

The Drizzle algorithm is pretty straightforward. See
