RE: filmscanners: VueScan 7.0.18 Available
What's new in version 7.0.18 * Changed processing to do infrared dust removal prior to restoring colors I know that your algorithms are different from what ASF does with ROC and ICE, but it looks like ASF does their ROC first, and then uses information from ROC to improve GEM. Part of the ROC algorithm identifies what portion of each pixel belongs to each dye layer. When the scan includes IR, this information can be used to help separate the RGBI layers. Using this should help isolate dust from actual image content. Does anybody have a Nikon scanner and could they check to see if ROC+ICE actually does better than just ICE for removal of dust? Or is this just something that was mentioned in the patents and never implemented in the commercial software? If fully implemented, it might allow reasonable dust removal from Kodachrome slides.

Using this should help isolate dust from actual image content. This is basically the order VueScan does things - ICE - ROC -GEM. The infrared dust removal gets done first, one pixel at a time without doing any smoothing or filling of dust spots. The restore colors is done next and then the last step of filtering the neighborhood around dust spots (or around film grain) is done. Regards, Ed Hamrick

I found a small problem with some Scan Dual II scanners in 7.0.17, so I fixed this and cleaned up a few other small things from my to-do list. You can download VueScan 7.0.18 from: http://www.hamrick.com/vsm.html What's new in version 7.0.18 * Fixed problem with Minolta Scan Dual II not always being recognized as connected to the computer * Changed File|Output to window to apply only to Scan - Preview is always displayed, regardless of this setting * Changed processing to do infrared dust removal prior to restoring colors * Made minor improvements to help file Regards, Ed Hamrick
