Re: Post something about yourself here (The Hello Thread)

The point of all this is to say that I’ve decided to become a writer/editor/publisher; there simply aren’t any paying jobs here, so I have to invent my own, which is a good thing, though difficult. You happen to be in a part of the world that's not that far from Don Lancaster, who's done someth...

Re: Software Requests (Besides Dewarping)?

hey, guys, we've talked about it in other threads, but what about page renumbering. You've got two cameras generating randomly named (but sequential) page image files. Generally, we put the images into left and right directories. It is really nice to have them renamed into something sequential that ...

Re: Output Background Color for Mixed & B/W

My father's been a software developer, running independent since 1980. He makes a living at it, a damn good one. One interesting quality about him: he doesn't knock other efforts... One night in church a couple years back someone asked the assistant pastor, "what about so and so." If you know anyth...

Re: ST Alternative

People willing to help generally don't have the necessary experience. Those who have it are either not participating in Open Source development at all, or are already engaged with another project. I do have a few small skills with software development. I could lend a hand if I knew where my contrib...

Re: ST Alternative

hey guys, Sartre said, hell is other people. I think we might have a non-technical issue with ScanTailor. Let me outline my understanding: I am grateful to Tulon for creating ScanTailor and I feel that I am in his debt. Tulon has done great work on ScanTailor, but he seems tired of it--like it's not...

Re: Vectorization

OCR is a pattern recognition problem. As such, it works in two parts: feature extraction and pattern classification. These two parts are tuned to work with one another. Feature extraction takes the raster and transforms it into a more compact representation. This more compact representation (hopeful...

Re: Automatic Page Turning

I'd be very interested in learning about any experiments on an electrostatic page lifting mechanism. I think such a thing should be possible and perhaps gentler on the paper than a vacuum or other mechanical page lifter.

Re: Custom DPI

Does it make any sense to image a ruler then count the pixels between the 1" and the 2" marks? Then use that as your DPI estimate.

a Bible is generally worse than a phone book, because its paper is more slippery.

Re: Scanner Build: "SAL|˩AƧ" by Univurshul

Shooting intentionally with a keystone is something I thought would never be a logical idea, but I'm beginning to consider all cards on the table, especially since the new software is crushing our old ideas of what's possible. This summer I vacationed in England and there were two occasions (C.S. L...
