Member Function Documentation

void TrainingSet::load ( const std::string pfx  ) 

Load feature and position vectors from a pair of .pfm files (such as those produced by save()).

<pfx>-features.pfm should contain the features associated with a series of frames, with nrows=NFRAMES and ncols=NFEATURES where NFEATURES is the number of features in the feature vector generated by whichever feature extractor produced this training set

<pfx>-positions.pfm should contain the eye position vectors associated with the same series of frames, with nrows=NFRAMES and ncols=W*H where W*H is the number of pixels in each image of the frame sequence

void TrainingSet::loadRebalanced ( const std::string pfx  ) 

Like load(), but rebalance the training set so that eye positions are included equally often.
