float vetHist::extractDifference (  vetHist *  compareHist  )

Returns mean absolute difference between histograms. Histograms must have same dimensionality and bands_per_dim. Parameters: hist  Pointer to Histogram to compare with this object Definition at line 310 of file vetHist.cpp. References extractProbs(), probHist, valBandwidth, and VETRET_ILLEGAL_USE.

VETRESULT vetHist::extractProbs (   )

Calculate histogram probabilities (probs) from frequencies (frequency_data) Definition at line 277 of file vetHist.cpp. References freqHist, probHist, probMax, probMin, valBandwidth, valCount, VETRET_ILLEGAL_USE, and VETRET_OK. Referenced by extractDifference(), fromImage(), and saveToXML().

VETRESULT vetHist::loadFromXML (  char const *  filename  )

Loads histogram from a (XML format) file. Definition at line 473 of file vetHist.cpp. References probHist, reset(), valCount, valMax, valMin, VETRET_OK, and VETRET_PARAM_ERR.

VETRESULT vetHist::saveToXML (  char const *  filename  )

Saves histogram data to an (XML format) file. Definition at line 424 of file vetHist.cpp. References extractProbs(), probHist, valBandwidth, valCount, valMax, valMin, VETRET_INTERNAL_ERR, VETRET_OK, and VETRET_PARAM_ERR.
