Detailed Description

Samples accumulator abstract class.

This class allows for storing samples (e.g. n-dimensinal points in feature space) into the memory

Constructor & Destructor Documentation

◆ CSamplesAccumulator() [1/2]

DirectGraphicalModels::CSamplesAccumulator::CSamplesAccumulator ( byte  nStates,
size_t  maxSamples 
)
inline

Constructor.

Parameters
nStatesNumber of states (classes)
maxSamplesMaximum number of samples to be used in training.

Default value 0 means using all the samples.
If another value is specified, the class for training will use maxSamples random samples from the whole amount of samples, added via addSample() function

Member Function Documentation

◆ addSample()

void DirectGraphicalModels::CSamplesAccumulator::addSample ( const Mat &  featureVector,
byte  state 
)

Adds new sample to the accumulator.

Parameters
featureVectorMulti-dimensinal point: Mat(size: nFeatures x 1)
stateState (class) corresponding to the featureVector

Here is the caller graph for this function:

◆ getNumInputSamples()

int DirectGraphicalModels::CSamplesAccumulator::getNumInputSamples ( byte  state) const

Returns the number of input samples in container for the state (class) state.

This function retunts the number of samples added with the addSample() function. Please note, that this number may be larger than the number of samples, actually stored in container, that may me true, if the constructor's argument maxSamples was specified. than the output of the getNumSamples()

Parameters
stateThe state (class)
Returns
The number of samples

Here is the caller graph for this function:

◆ getNumSamples()

int DirectGraphicalModels::CSamplesAccumulator::getNumSamples ( byte  state) const

Returns the number of stored samples in container for the state (class) state.

Parameters
stateThe state (class)
Returns
The number of samples

Here is the caller graph for this function:

◆ getSamplesContainer()

Mat DirectGraphicalModels::CSamplesAccumulator::getSamplesContainer ( byte  state) const
inline

Returns samples container for the state (class) state.

Parameters
stateThe state (class)
Returns
The container: Mat(size: nSamples x nFeatures)
