Creating seamless mosaic with aerial photography tiles

I have some aerial photography captured using a film camera, not digital.
As a result the image tiles I have all have a black border around them with various details on the photography.

What I would like to do is remove these black borders so that I can seamlessly mosaic the overlapping tiles together.

Does anyone know how this might be possible?  The 'nodata' areas have already been made transparent, and do not include the black borders.
