Gents, I found this thread while searching for dust removal software with ir channel. Recently I added infrared channel scan for my CS9000F (Pixma). Now I am thinking about implementing dust removal to the backend or to the frontend. Please send me your latest experiences about dust removal. I'm

Hello Andras, sorry for the delayed answer No better idea as working with a fixed ir thresholdbut I do not know if different films need different thresholds, did not much tests yet with different material.. Fixed a minor bug in my code (missed some pixels of the border around the ir t

Hello Andras, did some test with your 'duster' and with a very similar own algorithm, see http://www.ciselant.de/projects/antidust/ Your duster seems to miss some pixels and/or areas of dust. Maybe test if you hit enough random choosen pixel to calcuate the interpolation and iterate some times o

Hi all, I'm proud to make available the first testing version of a dust-removal facility for film scanners with IR readout. Currently it is a stand-alone tool, but the actual algorithm is implemented in a sanei library. The algorithm is so simple I can't think of a good reason why I didn't come up
