Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Compiled Tesseract with OpenCL enabled
2. Executed the GetUTF8Text() method.

What is the expected output? What do you see instead?
Supposed to extract the text from a given image faster than usual because 
OpenCL is enabled

What version of the product are you using? On what operating system?
tesseract 3.04.00
leptonica-1.71
zlib1.2.5

OpenCL info:
Found 1 platform.
  Platform name: Apple.
  Version: OpenCL 1.2 (Dec 14 2014 22:29:47).
  Found 2 devices.
    Device 1 name: Intel(R) Core(TM) i5-4250U CPU @ 1.30GHz.
    Device 2 name: HD Graphics 5000.
