You'll need to use geospatial software or libraries for this. GDAL is your best choice. gdal_translate with the -gcp option is what you want in this case. You can do the equivalent from gdal's Python interface, but it's a bit more involved. There's also a QGIS plugin to interactively build the GDAL command, if you'd like to interactively select the coregistration points.
