From d5168b503a5c3e26ed8f10232b6763b975eb7bd3 Mon Sep 17 00:00:00 2001 From: Jean-Michel Hautbois Date: Mon, 15 Feb 2021 17:29:17 +0100 Subject: ipa: Add a common interface for algorithm objects In order to instantiate and use algorithms (AWB, AGC, etc.) there is a need for a common class to define mandatory methods. Instead of reinventing the wheel, reuse what Raspberry Pi has done and adapt to the minimum requirements expected.
