Detailed Description

Diagonal Covariance class

DiagonalCovariance (istream &in) : Covariance(0)

DiagonalCovariance () : Covariance(0) , data(vector<double>(0,0.0))

DiagonalCovariance (int dim) : Covariance(dim) , data(vector<double>(dim,0.0))

Constructs a Diagonal Covariance with dimension dim

DiagonalCovariance (const DiagonalCovariance &cov) : Covariance(cov) , data(cov.data)

Copy Constructor

double mahalanobisDistance (const float *x1, const double *x2)

[const]

returns the mahalanobis distance between x1 and x2 using the covariance

Reimplemented from Covariance.

double& operator[] (int i)

virtual, should not be used

Reimplemented from Covariance.

double& operator() (int i)

virtual, should not be used

Reimplemented from Covariance.

double& operator() (int i,int)

virtual, should not be used

Reimplemented from Covariance.

void compute_determinant ()

[const]

Computes the determinant

Reimplemented from Covariance.

void accumFrame (const float *v)

accumulates a frame to the covariance

Reimplemented from Covariance.

void accumFrame (const vector<float> &v)

accumulates a frame to the covariance

Reimplemented from Covariance.

void reset ()

Reset accumulation to zero

Reimplemented from Covariance.

Covariance * copy ()

Returns a copy of the covariance

Reimplemented from Covariance.

void invert ()

Converts from accumulate mode to real

Reimplemented from Covariance.

void processMean (RCPtr<Mean> mean)

Substract mean^2, before the covariance can be inverted

Reimplemented from Covariance.

void printOn (ostream &out=cout)

[const virtual]

print function used for operator <<

Reimplemented from Covariance.

void readFrom (istream &in=cin)

Read function used for operator >>

Reimplemented from Object.

friend istream & operator >> (istream &in, DiagonalCovariance &cov)

extractor operator

friend class GMM

inline Covariance * NewDiagonalCovariance (int dim)

Function that acts as a factory for diagonal covariance

istream & operator >> (istream &in, DiagonalCovariance &cov)
