    "title": "A Perception-Based Threshold for Bidirectional Texture Functions",
    "subtitle": null,
    "abstract": "For creating photorealistic images, Computer Graphics re-searchers introduced Bidirectional Texture Functions (BTFs),which use view- and illumination-dependent textures for ren-dering. BTFs require massive storage, and several proposalswere made on how to compress them, but very few take intoaccount human perception. We present and discuss an exper-imental study on how decreasing the texture resolution influ-ences perceived quality of the rendered images. In a visualcomparison task, observer quality judgments and gaze datawere collected and analysed to determine the optimal down-sampling of BTF data without significant loss of their per-ceived visual quality.",
