Had a look at the last two papers. It all looks pretty straightforward – though the devil will be in the detail as they themselves admit, care is needed to ensure the implementation is robust against residual defects, cosmic rays and artefacts. Would be fairly easy (though fiddly) to implement in something like Python – shame some of the commercial packages go for the simple solutions only – its not as if CPU and memory is expensive anymore.
It was surprisingly familiar as I saw similar methods presented at an SPIE conference in 2003 or 2005 (cannot check as work went “smart working” a year or two back and lots of conference proceedings got thrown out when we lost book shelves) where there was a session on dim source tracking techniques.
Will have a look at the other paper on Tuesday and report back.
