[FFmpeg-devel] [PATCH 09/11] tests/swscale: calculate theoretical expected SSIM

2025-03-17 Thread Niklas Haas
From: Niklas Haas We can calculate with some confidence the theoretical expected SSIM from an "ideal" conversion, by computing the reference SSIM level for an image dithered with uniformly distributed quatization noise. This gives us an additional safety net to check for regressions even in the
