Public Attributes | |
| CppWrapperInternal::WrappedClass | wrappedClass_ |
Holds all information related to a single character, such as nominal and average position, reference quality indicators,... During the learning phases, it also keeps the list of its constituent blobs.
The statistics available for each character are the average, standard deviation (unbiased), minimum and maximum computed on the corresponding parameters for all images for which EOCV::UpdateStatistics has been invoked after inspection. The average is only available when at least one set of results has been accumulated. The standard deviation is only available when at least two sets of results have been accumulated.
