Re: Detection depends on exact image.

Hi Mr. Sriranga, I think maybe because his files are JPEG the conversion to BMP produced a low quality file. Perhaps if you use a manual conversion -- not copy and paste -- it will produce different results? I'm pretty sure the dark line at the bottom and the lack of border / margins are the proble

My answer can add to Sven's. Although close edges can be indeed a problem, and Tesseract feels better when a bigger background area surrounds the target text, probably you'd want to pay attention to the lower edge of the "Sheoldred One.jpg" image. There's a thin dark line along the edge - that's th

So, it looks like the text is too close to the edge. That is a known problem. Perhaps you could manipulate the image to add space around the image. ImageMagick and other libraries/tools can easily do that with little CPU utilization. --Sven On Tue, Aug 30, 2011 at 10:08 AM, Rick Appleton wrote:

Thanks Dmitri for your reply. If suppose I want to put my 'eng.traineddata' in 'D:\' and I want to run tesseract. Where should I change the path for "TESSDATA_PREFIX" to read the eng.traineddata from D drive? On Tue, Aug 30, 2011 at 11:15 AM, Dmitri Silaev wrote: > Given that you run Tesseract wh
