◆ CheckInferenceTimeThreshold()

bool CheckInferenceTimeThreshold	(	const std::chrono::duration< double, std::milli > &	duration,
		const double &	thresholdTime
	)

Given a measured duration and a threshold time tell the user whether we succeeded or not.

Parameters

duration	the measured inference duration.
thresholdTime	the threshold time in milliseconds.

Returns: false if the measured time exceeded the threshold.
