Header file for MEX-functions that use ML module from OpenCV library. This file includes maps for option processing, as well as functions for creating instances of classes from parsed arguments.

Definition in file mexopencv_ml.hpp.

Function Documentation

createTrainData()

cv::Ptr<cv::ml::TrainData> createTrainData	(	const cv::Mat &	samples,
		const cv::Mat &	responses,
		std::vector< MxArray >::const_iterator	first,
		std::vector< MxArray >::const_iterator	last
	)

Create an instance of TrainData using options in arguments.

Parameters

samples	data samples
responses	data responses
first	iterator at the beginning of the vector range
last	iterator at the end of the vector range

Returns

smart pointer to created cv::ml::TrainData

Definition at line 70 of file mexopencv_ml.cpp.

loadTrainData()

cv::Ptr<cv::ml::TrainData> loadTrainData	(	const std::string &	filename,
		std::vector< MxArray >::const_iterator	first,
		std::vector< MxArray >::const_iterator	last
	)

Read a dataset from a CSV file.

Parameters

filename	The input CSV file name
first	iterator at the beginning of the vector range
last	iterator at the end of the vector range

Returns

smart pointer to created cv::ml::TrainData

Definition at line 134 of file mexopencv_ml.cpp.
