Patent number: 11282258Abstract: Image quality can be improved by rendering the image based on an importance map that indicates regions of the image that will benefit from more samples. Adaptive sampling determines a number of samples for each pixel of the image using a target sampling rate and the importance map for the image. The number of samples for each pixel needs to be a non-negative integer value, so the per-pixel sampling rates are quantized using per-pixel random values. The resulting quantized sampling rates provides a distribution of samples that closely matches the importance map. The per-pixel random values may vary over time so that the average of the distribution more closely matches the importance map.Type: GrantFiled: February 9, 2021Date of Patent: March 22, 2022Assignee: NVIDIA CorporationInventors: Tomas Guy Akenine-Möller, Jim Kjell David Nilsson, Johan Pontus Andersson
