Member Data Documentation

adapted

int tesseract::ViterbiStateEntry::adapted

associate_stats

AssociateStats tesseract::ViterbiStateEntry::associate_stats

competing_vse

ViterbiStateEntry* tesseract::ViterbiStateEntry::competing_vse

Pointer to a case-competing ViterbiStateEntry in the same list that represents a path ending in the same letter of the opposite case.

consistency_info

LMConsistencyInfo tesseract::ViterbiStateEntry::consistency_info

cost

float tesseract::ViterbiStateEntry::cost

The cost is an adjusted ratings sum, that is adjusted by all the language model components that use Viterbi search.

curr_b

BLOB_CHOICE* tesseract::ViterbiStateEntry::curr_b

Pointers to BLOB_CHOICE and parent ViterbiStateEntry (not owned by this).

dawg_info

LanguageModelDawgInfo* tesseract::ViterbiStateEntry::dawg_info

Extra information maintained by Dawg language model component (owned by ViterbiStateEntry).

debug_str

STRING* tesseract::ViterbiStateEntry::debug_str

UTF8 string representing the path corresponding to this vse. Populated only in when language_model_debug_level > 0.

length

int tesseract::ViterbiStateEntry::length

min_certainty

float tesseract::ViterbiStateEntry::min_certainty

ngram_info

LanguageModelNgramInfo* tesseract::ViterbiStateEntry::ngram_info

Extra information maintained by Ngram language model component (owned by ViterbiStateEntry).

outline_length

float tesseract::ViterbiStateEntry::outline_length

parent_vse

ViterbiStateEntry* tesseract::ViterbiStateEntry::parent_vse

ratings_sum

float tesseract::ViterbiStateEntry::ratings_sum

Various information about the characters on the path represented by this ViterbiStateEntry.

top_choice_flags

LanguageModelFlagsType tesseract::ViterbiStateEntry::top_choice_flags

Flags for marking the entry as a top choice path with the smallest rating or lower/upper case letters).

updated
