Detailed Description

Abstract Input Class defining the interface for a video sequence input type.

Constructor & Destructor Documentation

viva::Input::Input ( const Size &  size = Size(-1, -1), int  conversionFlag = -1  )

inline

Input class constructor

Parameters

size	force the input class to an specific size resolution. Default value of (-1,-1) will use the original medium resolution.
conversionFlag	OpenCV conversion flag e.g., CV_RGB2GRAY. Default value of -1 will do not convert the original feed.

virtual viva::Input::~Input ( )

inlinevirtual

Virtual desctructor

Member Function Documentation

virtual bool viva::Input::getFrame ( Mat &  image )

pure virtual

Obtain an image frame from the input

Parameters

image

output image from the input.

Returns

bool: whenever an image was retrieved or not from the input.

Implemented in viva::ImageListInput, and viva::VideoInput.

size_t viva::Input::getHeight ( )

inline

Returns the image's height of the input feed

Size viva::Input::getOrgSize ( )

inline

Returns the original input size. This will be the same to the current image's width and height if it's created with size(-1,-1).

size_t viva::Input::getWidth ( )

inline

Returns the image's width of the input feed.

void viva::Input::setConversionType ( int  flag )

inline

Set the OpenCV conversion flag value e.g., CV_BGR2GRAY. Any posterior call to processFrame will return an image using this conversion type flag.
