I'm teaching an undergraduate linear algebra course, and looking for applications. The New Horizons spacecraft is approaching Pluto, and returning images I find fascinating: http://pluto.jhuapl.edu/index.php
They briefly refer to 'image deconvolution'. I expect they are using the most sophisticated tools available, some nonlinear, but my vague understanding is that some simple methods are linear algebra based.
Can anyone provide a reference or expository paper on linear algebra methods for image deconvolution that would be a good starting point?
