New issue 1497 by chentaokite: Different OCR results for windows and CentOS
https://code.google.com/p/tesseract-ocr/issues/detail?id=1497

What steps will reproduce the problem?
Execute "tesseract pure_text.png pure_text_win" on windows7 and
"tesseract pure_text.png pure_text_centos" on CentOS6.4

Both window7 and CentOS6.4 have installed tesseract 3.02.02

What is the expected output? What do you see instead?
The two outputs are expected to be identical or very similar. However, they
are very different: window's result is almost perfect, while the result by
CentOS is terrible. Please see the attachments for details.


What version of the product are you using? On what operating system?

windows7:
tesseract 3.02
leptonica-1.68 (Mar 14 2011, 10:43:03) [MSC v.1500 LIB Release 32 bit]
libgif 4.1.6 : libjpeg 8c : libpng 1.4.3 : libtiff 3.9.4 : zlib 1.2.5

CentOS6.4
tesseract 3.02.02
leptonica-1.72
libjpeg 6b (libjpeg-turbo 1.2.1) : libpng 1.2.49 : zlib 1.2.3


Please provide any additional information below.
Tesseract on CentOS is observed to perform worse than windows for many
other pictures.
