Detailed Description

bin_width = (max - min)/nbins ith bin (zero-based indexing) contains [i*bin_width, (i+1)*bin_width) with an exception that (nbins - 1)th bin contains [(nbins-1)*bin_width, nbins*bin_width]

Make sure to call Finalize before GetHistogram to reduce per-thread histogram.

void dnnlowp::Histogram::Add	(	const float *	f,
		int	len
	)

This version collects histogram with multiple threads using per-thread histogram with privatization.

We should call Finalize before GetHistogram to reduce per-thread histogram.

void dnnlowp::Histogram::Finalize

(

)

Reduce per-thread histogram.

Need to call this before GetHistogram when the version of Add with multiple threads was used.
