Constructor & Destructor Documentation

PipeLineAction()

PipeLineAction::PipeLineAction

(

const cv::String

name

)

Constructor.

Parameters

name	(screen)name of the pipeline action

    img = cv::Mat::zeros(cv::Size(1, 1), CV_8SC3);
    show = false;
    this->name = name;
}

Member Function Documentation

setAction()

virtual void PipeLineAction::setAction ( void *  data )

pure virtual

sets the output of the action

The parameter type is kept open, this provides the possibility to change the order of the pipeline and the type of parameter which is inserted. Special precautions have been taken to check if the parameter type is suitable for the action.

Parameters

data	pointer to the input data

Implemented in Moment, Mask, ConvertColorSpace, Contour, and Blur.

getAction()

void * PipeLineAction::getAction ( )

virtual

gets the output of the action

The return type is kept open, this provides the possibility to have different outputs bassed on the implementation in the iherited class

Returns

data: pointer to the image matrix

Reimplemented in Moment, and Contour.

{
    return &img;
}

showWindow()

virtual void PipeLineAction::showWindow ( )

pure virtual

shows the action to the user

uses cv::imshow(). The name of the window is the name of the pipeline action. it is possible to add trackbars to the implentations.

Implemented in Moment, Mask, ConvertColorSpace, Contour, and Blur.

hideWindow()

void PipeLineAction::hideWindow

(

)

hides the action to the user

destroys the OpenCV window based on the pipeline action name.

{
    if (show) {
        cv::destroyWindow(name);
        show = false;
    }
}

getName()

cv::String PipeLineAction::getName

(

)

gets the pipeline action name

Returns

name: (screen)name of the pipeline action.

{
    return name;
}
