Can I configure Tesseract to *always* match a dictionary word?

2012-03-21 Thread aidano
I'd like to configure tesseract with a small dictionary (~200 words) and tell it to always choose the best match in the dictionary. Is that possible? Also, when inspecting the source code I saw a variable in dict.h called "user_patterns_suffix". Is there any documentation around this? I'd like t

Hello, I've trained tesseract with only this characters: 0123456789-. I used one tiff with this characters, with 6 samples of each. After the successfully training, tesseract only recognize if in the input tiff there are more than 3 numbers. With a tiff with, for example this numbers 65 it retur

Adding a call to SetInputName("") in my setup routine seemed to work! But may I ask *why* that worked? I'd assume that everything should be handled in tesseract::Init() - is there other functionality that Init doesn't take care of? Thanks! (Also, I'm using XCode over here - easiest way to get st

Can you post your images? It's hard to comment without any images. What resolution are you working with? On Thursday, March 15, 2012 3:27:00 AM UTC-7, Rufus wrote: > > Hello everyone, > > There is something which I don't quite understand about how tesseract > works internally. > > I've taken

Hi, you can try to call SetInputName() before calling GetHOCRText(). Are you using eclipse CDT? If yes it should be straightforward to import tesseract as a makefile project and debug into the code yourself, if need be. Cheers Renard Am Sonntag, 18. März 2012 20:24:16 UTC+1 schrieb Jesse Fu

a small addendum to my earlier post: perhaps the feature I requested could, or even would NEED to: * optionally dump the transformed (rotated and deskewed) version of the image. (The version which tesseract works from, internally) * inverse-rotate the coordinates for the said box file, so that
