I would like to use tesseract to read data from a scanned high school transcript. The form contains a bunch of fields (student name, gender, address) and corresponding values (characters, words or numbers).
I understand the way to do this is using config files augmented with user data [see the man page <http://tesseract-ocr.googlecode.com/svn/trunk/doc/tesseract.1.html>, patterns are explained in more detail in the file /path/to/tesseract-ocr/dict/trie.h]. However, when I try to set my own eng.user-words or eng.user-patterns, tesseract returns a *Segmentation Fault*. First, here is a test image I am using to check the pattern matching: (attached file test-002.png) Here is some info about my install: cs@pleco:/data/OCR/tesseract/tests$ lsb_release -a No LSB modules are available.
