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.
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.
