Name	Description	Size	Coverage
corner_match_avx2.c	Compute mean and standard deviation of pixels in a window of size MATCH_SZ by MATCH_SZ centered at (x, y). Store results into mean and one_over_stddev Note: The output of this function is scaled by MATCH_SZ, as in mean = MATCH_SZ * <true mean> and one_over_stddev = 1 / (MATCH_SZ * <true stddev>) Combined with the fact that we return 1/stddev rather than the standard deviation itself, this allows us to completely avoid divisions in aom_compute_correlation, which is much hotter than this function is. Returns true if this feature point is usable, false otherwise.	5442	0 %
