[bcab] Re: FineReader OCR

Hi Vince

Thanks for suggestion - I think it has a document mode which I think is the 
same as a monochrome mode. I will have a play with that - if it works as well 
then it will make file sizes smaller and work faster. Camera is 8 megapixel so 
gives me about 300 dpi on an A4 page which I think is about optimum for OCR.  
The aim eventually is to have a set-up that will read anything perfectly 
without individual fiddling with the file - although I appreciate this may mean 
the software having to try things out and be self-adaptive.

Regards
Tony

  Tony, for what it's worth I find it can simplify things to convert scanned 
images to grey-scale and then adjust the brightness and shadow settings in a 
graphics program so that the text stands out more - and sometimes it makes it 
clearer if you make the image negative. Depends so much on all your hardware 
and your vision, I suppose.

  Someone shoed me the 'document' mode on their digital camera, and I must say 
there's a lot of potential there for creating the equivalent of a scanned 
image. I think the spec of the camera was about 6 megapixels, which is fairly 
standard now.

  Vince.

    Hi

    I have recently been doing some tests with FineReader OCR on difficult to 
read material - text over coloured backgrounds and photographs. (Specifically 
the backs of paperback books).

    I have been using both FineReader 7 and FineReader 8. Oddly enough, 7 
performs this much better than 8 - it is faster and far, far more accurate 
(often 100%!).

    I have also found that successive scans on my cheapo Xerox flatbed scanner 
give different errors, so I assume this is down to fluctuations in the 
scanner's physical performance. Successive photos with a digital camera do not 
give this problem.

    I would be deeply interested to hear of anyone elses experiences, 
experiments and setups for OCR.

    Regards
    Tony
