Detailed Description

Class for I/O of OpenCV images via command line.

Here we demonstrate what needs to be done to add data I/O providers for specific data types to the Alida framework.
In this case a provider for the OpenCV image data type IplImage is defined used in conjunction with the corresponding operator DemoOperatorOpenCV.

Member Function Documentation

void * OpenCVImageDataIO::readData	(	std::string	input,
		std::string	type
	)		const [virtual]

Function to open an image from given filename.

This function interprets the given input string as filename and tries to read an image from the specified location.

Parameters:

input	Name of file to be read.
type	Image type requested.

Returns:

Generated openCV image.

Implements Alida::ALDDataIOCmdline.

Definition at line 69 of file OpenCVImageDataIO.cc.

string OpenCVImageDataIO::writeData	(	std::string	format,
		std::string	type,
		void *	data
	)		const [virtual]

Function to output an image to file or screen.

This function outputs/displays a given image. If the format string just contains "-", the image is displayed on screen, otherwise the format string is interpreted as filename where to save the image. The returned string is empty in both cases.

Parameters:

format	Output filename.
type	Identifier string for object type.
data	Image to be displayed/saved.

Returns:

Empty string.

Implements Alida::ALDDataIOCmdline.
