问题
I am trying to use Tesseract OCR Library in order to create a program to read pictures of elevator floor numbers. I haven't found any example on how to include the Tesseract Library into a C++ file. Something like:
#include "tesseract.h"
I am using Tesseract v 3.00 on Ubuntu 10.10.
回答1:
The PlatformStatus Page has some comments on how to install it. It has dependencies (leptonica) which also need to be installed.
Another solution also linked from the above discussion has similar details for other linux distributions.
When it comes to linking with your program, this post has some specifics
There is also a C wrapper to the underlying API calls; looking at the files included should tell you what to include. Other wrappers are available here.
The documentation of the base API class are here...
A comment from the Platform Status page for the installation.
