Re: IXUS 160 Focal Plane

Might be interesting to see the ScanTailor result of that same page without using your image averaging step. What ISO setting are you using?

Re: software to automatically remove fingers?

I'd try something like these, as they are cheap and would offer a bit of grip that would help to turn pages: Harbor Freight 9 mil Black Nitrile Gloves If I were using my thumbs in the outer margins to hold the book open while shooting (i.e. not using a platen to hold down the pages), I'd use a blue ...

Re: AABBYY Fine Reader and I

I too began my quest to scan all the books from my personal library as ePub. I soon discovered the same issue with AABBYY that you did in that this takes a LOT of hand tweaking to correct all of the OCR and formatting mistakes. I finally gave up and decided to save the books as PDF using Adobe Acrob...

ScanTailor Performance Affected by Meltdown/Spectre Bug Patch?

Has anyone done a comparison of ScanTailor's performance before and after installing Microsoft's Meltdown bug patch?

Re: Converting Color/Grayscale Text Scans to Black & White

Are you in some way affiliated with CZUR?

You've replied to a number of posts on this website and it's always recommending the purchase of a CZUR scanner. This seems like spam to me, but I'll let the moderators decide this or not.

Re: [Flatbed] Putting weight on the spine

Something else you could try is to use a hinged lever to put downward pressure on the book's spine. That would make it easier easier on your hands at the expense of having to lift the lever each time you turned the page.

Re: chdlptp problems

I've never attempted using PTP to camera loaded with CHDK but since no one else has chimed in maybe some of the things mentioned in this will help: CHDK PTP Extension Wiki FAQ.

Re: Advice on Lighting

I made something similar to this as a quick prototype in order to acquire enough sample images to work on my software post-processing pipeline prior to building a more substantial scanner. My design differed from yours in that rather than have the camera pointing up, I made a horizontal rectangular ...

Re: [Flatbed] Putting weight on the spine

For something that would put weight on it, how about a bag of water? It would be nice and flexible, so it would match the contour of the book and you could add more weight by using more water. If you want something flat you could use a board and put a jug of water on top of that. Maybe sand (for ex...
