Constructor & Destructor Documentation

HumanDetector::HumanDetector

(

void

)

Default constructor.

Definition at line 23 of file human_detector.cpp.

Member Function Documentation

std::vector< cv::Rect > HumanDetector::detectHuman2D

(

const cv::Mat &

input_img

)

Detects humans from a cv::Mat.

Parameters

input_img

[const cv::Mat&] The input image

Returns

[std::vector<cv::Rect>] A vector containing the detected humans. Each human is represented by a rectangle.

Definition at line 46 of file human_detector.cpp.

std::vector< cv::Rect > HumanDetector::detectHuman2D ( const cv::Mat &  input_img, const std::string &  haar_path  )

private

Detects humans from a cv::Mat.

Parameters

input_img	[const cv::Mat&] The input image
haar_path	[const std::string] The Haar training model path

Returns

[std::vector<cv::Rect>] A vector containing the detected humans. Each human is represented by a rectangle.

Definition at line 80 of file human_detector.cpp.

std::vector< cv::Rect > HumanDetector::findHuman2D

(

std::string

file_name

)

Finds humans in an image retrieved from a file URL.

Parameters

file_name

[std::string] The image file's URL

Returns

[std::vector<cv::Rect>] A vector containing the detected humans. Each human is represented by a rectangle.

Definition at line 166 of file human_detector.cpp.

std::vector< cv::Rect > HumanDetector::identifyUniqueHumans ( const std::vector< cv::Rect >  pedestrianVector, const std::vector< cv::Rect >  upperbodyVector  )

private

Identify unique humans from two sets of humans.

Parameters

pedestrianVector	[const std::vector<cv::Rect>&] The first set of humans
upperbodyVector	[const std::vector<cv::Rect>&] The second set of humans

Returns

[std::vector<cv::Rect>] A vector containing the unique humans. Each human is represented by a rectangle.

Definition at line 139 of file human_detector.cpp.

cv::Mat HumanDetector::loadImage

(

std::string

file_name

)

Loads an image from a file URL.

Parameters

file_name

[std::string] The image's file URL

Returns

[cv::Mat] The image in OpenCV representation
