From 9ce7bf835a8dceca891dbce05fecd5b5417b3856 Mon Sep 17 00:00:00 2001 From: Paul Wilkins Date: Thu, 28 Feb 2019 13:19:11 +0000 Subject: [PATCH] Store a group level noise metric from first pass. Adds a variable to GF group structure to store a noise energy metric for the current group that can be used in things like film grain retention code.
