Detailed Description

Recieves frames (as cv::Mat), processes them (ideally asynchronously) and emits them as a QImage (i.e.

for use in a QWidget)

Member Function Documentation

void FrameConverter::process	(	cv::Mat	frame,
		ColorSpace	cs
	)

private

Actually process a frame.

Resultant QImage gets emitted by imageReady()

void FrameConverter::processFrame	(	const cv::Mat &	frame,
		enum	ColorSpace
	)

slot

Add a new frame to be processed; if not processAll this frame may yet be dropped.

private

Queue a new frame to be processed (depends on processAll if it gets processed).

void FrameConverter::timerEvent ( QTimerEvent * ev )

private

Called each time that mTimer ticks...

we call process on the queue in here.
