Member Data Documentation

classIdx

int cv::ml::DTrees::Node::classIdx

Class index normalized to 0..class_count-1 range and assigned to the node.

It is used internally in classification trees and tree ensembles.

defaultDir

int cv::ml::DTrees::Node::defaultDir

Default direction where to go (-1: left or +1: right).

It helps in the case of missing values.

left

int cv::ml::DTrees::Node::left

Index of the left child node.

parent

int cv::ml::DTrees::Node::parent

Index of the parent node.

right

int cv::ml::DTrees::Node::right

Index of right child node.

split

int cv::ml::DTrees::Node::split

Index of the first split.

value

double cv::ml::DTrees::Node::value

Value at the node: a class label in case of classification or estimated function value in case of regression.
