We had great results using tesseract-ocr[1] with SWT (state of the art text detection algorithm, via libccv[2]) on Linux.
You can use our python bindings for both[3,4], although they might be slightly outdated:

- MrBuddyCasino 12y agoIs it still possible to generate pixel correct hOCR when using SWT? Also, what is the main advantage of SWT - improving speed or accuracy?
- steeve 12y agoI'm not sure about speed, but for accuracy, it's great. We've had terrible results with tesseract when giving it text that wasn't properly cropped with SWT.
- MrBuddyCasino 12y agoThanks, I use Tesseract in a product I'm developing, I'll try using SWT then.
- danbruc 12y agoBe aware that SWT is patented [1] if you want to use it commercially. [1] http://www.google.com/patents/US20090285482 http://www.google.com/patents/US20090285482
- discjockeydom 12y agoThis link shows the claims of the published application. The recently allowed claims are a lot more narrow and less problematic. Still worth reviewing though in case you are worried you infringe: http://www.scribd.com/doc/240266916/12122729 http://www.scribd.com/doc/240266916/12122729
- ap22213 12y agoIt looks like Microsoft is the assignee? If so, is this included in the Microsoft OCR library?
- beagle3 12y agoWhat did you use to generate pyccv? (It looks automatically generated) Does it still work with an up-to-date ccv?
