Re: Another book shooter Mk-V

Good progress, and your image enhances quite well with a simple levels adjustment, although I had to use quite aggressive settings that may have had some adverse effect on the image if it is examined closely: IMG-20190210-191017_Levels.jpg With a less aggressive adjustment there was still some varia...

Re: OCR for 78 RPM record labels

If I were going to do this I'd get a 12"x12" piece of 1/4" MDF, put a 1/4" dowel coming out the center of it and stick that to the wall with double-stick tape. I'd put a camera on a tripod about 6' back, pointed at that dowel, and have two clip-on lights to the right and left of the tripod to light...

Re: OCR for 78 RPM record labels

Small detail: your laser level marker idea is neat, but I doubt if it is needed as in another quick test, text rotated by 2º was read successfully by the Abbyy screen reader, and text can be eyeballed horizontal to a much closer tolerance than that.

Re: OCR for 78 RPM record labels

Thanks for the reply. I thought of a using a spindle, the catch there is that the Archivist has a "V" shaped tray that gets elevated to the underside of a likewise "V" shaped glass platen (2 camera system,) so I would need to use something of a height and material that would not damage the glass. T...

Re: OCR for 78 RPM record labels

Some further thoughts a day on... You don't give any indication of the facilities you have available, but a better solution to the registration issue might be to place a piece of some sheet material such as plywood on top of each book rest. Those pieces could be fitted with either record center regi...

Re: OCR for 78 RPM record labels

Continuing from your previous post scanning & processing 78 RPM record labels : I suggested that the registration problem might be easily overcome by [non-destructively for later book scanning] temporarily inserting some kind of round pin into each side of the book rest. You would have to find somet...

Re: digitizing antique magazines

I do have a piece of acrylic that I can use to flatten the pages.. Is there such a thing as an anti glare coating that I could apply? I'm not immediately aware of anything suitable but there are a variety of anti-reflective glass sheets available, although their use may at least slightly reduce the...

Re: digitizing antique magazines

Are you able to image a full page into the gutter, and preferably post the file output from ScanSnap so that any possible alternative software dewarping solution can be tested to best effect? If you are unable to capture full pages satisfactorily, a better solution might be to use a classic book sca...

Re: scanning & processing 78 RPM record labels

No-one else has replied yet so perhaps I can give some thoughts as a start: o The Archivist Quill Scanner which you already have has two features intended for book scanning that are not really relevant to your project: first, it is designed to flatten the pages of a book, but the records you need to...
