From d48a18c9f253e7d4f709a3e9b126fde9f164f08d Mon Sep 17 00:00:00 2001
From: Zhao Halley <halley.zhao@intel.com>

Subject: [PATCH] tests: filter: add support for denoising and sharpening.

Add --denoise option to enable noise reduction with the level specified
as the option value (float). Likewise, add --sharpen option to enable
sharpening.
