java.lang.Object org.opencv.ml.CvParamGrid
public class CvParamGrid
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.

public CvParamGrid()
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;
