Addition of Tesseract GetRegions/GetWords to API #9

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
An improvement request--

Would like to have methods for returning Tesseract Region/Word bounding boxes 
added to the Android API. The following functions in Tesseract's baseapi.cpp 
would do it, I think, with a result returned as ArrayList<Rect> or Pixa:

TessBaseAPI::GetRegions
TessBaseAPI::GetWords

Having these bounding boxes available would be helpful for assessing the 
coverage and quality of the results returned from the OCR engine beyond what's 
already available using meanConfidence() and wordConfidences().

For anyone who's interested, I've added these functions to my fork of this 
project at https://github.com/rmtheis/tess-two.

I've also added a third function, TessBaseAPI::GetCharacters, that returns 
bounding boxes for individual characters.

In Application.mk, you add:
APP_PLATFORM := android-9

good luck!
