Detailed Description

A class for detection using Cascade classifiers.

Given a scene and a cascade classifier, this class performs a classification and returns detections. The training is not supported in OD currently but is compatible to the cascade training of OpenCV. Train your cascade classifiers using OpenCV's opencv_traincascade utility (http://docs.opencv.org/master/dc/d88/tutorial_traincascade.html#gsc.tab=0). It is a great tool for traning your cascade. Paste the generated xml in trained_data_location_/TD_CASCADE/*.cascade.xml to use your trained cascade.

Member Function Documentation

ODDetections* od::g2d::ODCascadeDetector::detect ( ODSceneImage * scene )

virtual

Function for performing detection on a segmented scene.

The purpose of this function is to perform detection on a segmented scene or an 'object candidate'. i.e. the entire scene is considered as an 'object' or an detection. It is possible for a scene to trigger multiple detections.

Parameters

[in] scene An instance of 2D scene

Returns: [out] detections A number of detections as an ODDetections instance.

Implements od::ODDetector2D.

ODDetections2D* od::g2d::ODCascadeDetector::detectOmni ( ODSceneImage * scene )

virtual

Function for performing detection on an entire scene.

The purpose of this function is to detect an object in an entire scene. Thus, other than the type of detection we also have information about the location of the detection w.r.t. the scene.

Parameters

[in] scene An instance of 2D scene

Returns: [out] detections A number of detections as an ODDetections2D instance containing information about the detection and its 2D location.

Implements od::ODDetector2D.

void od::g2d::ODCascadeDetector::init ( )

inlinevirtual

Implements od::ODDetectorCommon.
