Class CvParamGrid

java.lang.Object

org.opencv.ml.CvParamGrid

public class CvParamGrid
extends Object

The structure represents the logarithmic grid range of statmodel parameters. It is used for optimizing statmodel accuracy by varying model parameters, the accuracy estimate being computed by cross-validation.

Minimum value of the statmodel parameter.

Maximum value of the statmodel parameter.

// C++ code:

Logarithmic step for iterating the statmodel parameter.

The grid determines the following iteration sequence of the statmodel parameter values:

(min_val, min_val*step, min_val*(step)^2, dots, min_val*(step)^n),

where n is the maximal index satisfying

min_val * step ^n < max_val

The grid is logarithmic, so step must always be greater then 1.

The constructors.

The full constructor initializes corresponding members. The default constructor creates a dummy grid:

// C++ code:

CvParamGrid.CvParamGrid()

min_val = max_val = step = 0;
