    • FLIP: A Difference Evaluator for Alternating Images 

      Andersson, Pontus; Nilsson, Jim; Akenine-Möller, Tomas; Oskarsson, Magnus; Åström, Kalle; Fairchild, Mark D. (ACM, 2020)
      Image quality measures are becoming increasingly important in the field of computer graphics. For example, there is currently a major focus on generating photorealistic images in real time by combining path tracing with ...

    • Luminance-Preserving and Temporally Stable Daltonization 

      Ebelin, Pontus; Crassin, Cyril; Denes, Gyorgy; Oskarsson, Magnus; Åström, Kalle; Akenine-Möller, Tomas (The Eurographics Association, 2023)
      We propose a novel, real-time algorithm for recoloring images to improve the experience for a color vision deficient observer. The output is temporally stable and preserves luminance, the most important visual cue. It runs ...

    • Spatiotemporal Blue Noise Masks 

      Wolfe, Alan; Morrical, Nathan; Akenine-Möller, Tomas; Ramamoorthi, Ravi (The Eurographics Association, 2022)
      Blue noise error patterns are well suited to human perception, and when applied to stochastic rendering techniques, blue noise masks can minimize unwanted low-frequency noise in the final image. Current methods of applying ...

    • Temporally Dense Ray Tracing 

      Andersson, Pontus; Nilsson, Jim; Salvi, Marco; Spjut, Josef; Akenine-Möller, Tomas (The Eurographics Association, 2019)
      We present a technique for real-time ray tracing with the goal of reaching 240 frames per second or more. The core idea is to trade spatial resolution for faster temporal updates in such a way that the display and human ...

    • Tight Bounding Boxes for Voxels and Bricks in a Signed Distance Field Ray Tracer 

      Hansson-Söderlund, Herman; Akenine-Möller, Tomas (The Eurographics Association, 2023)
      We present simple methods to compute tight axis-aligned bounding boxes for voxels and for bricks of voxels in a signed distance function renderer based on ray tracing. Our results show total frame time reductions of 20-31% ...

    • Visualizing Errors in Rendered High Dynamic Range Images 

      Andersson, Pontus; Nilsson, Jim; Shirley, Peter; Akenine-Möller, Tomas (The Eurographics Association, 2021)
      A new error metric targeting rendered high dynamic range images is presented. Our method computes a composite visualization over a number of low dynamic range error maps of exposure compensated and tone mapped image pairs ...
