Class CvParamGrid

java.lang.Object
  extended by org.opencv.ml.CvParamGrid

public class CvParamGrid
extends java.lang.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.

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.
