Overview: In this topic NVIDIA is going to discuss latest advancements in non-DL based denoising. Basing on previous work from Metro Exodus, a new method has been introduced which is based on recurrent blur too, but it has got a lot of improvements, like: better overall performance, cleaner results, specular denoising support, fast data reconstruction, better bilateral weighting and some others. Besides the algorithm overview the topics will be covered in the talk:n- mipmapping of incoming radiance - is it worth it?n- proper controlling of blur radius to avoid over-blurringn- accurate dis-occlusion detectionn- specular tracking without specular motionn- fast and high amplitude noise free data reconstruction of regions with discarded historyn- exponential versus linear accumulation. Why linear accumulation is better?n- how to compute bilateral weights in spatial passes?n- input signal compression - should it be used or not?n- how to fight with temporal lag
