  1. Comprehensive characterization of human color discrimination thresholds

    Publication
    Color discrimination thresholds—the smallest detectable color differences—provide a benchmark for models of color vision, enable quantitative evaluation of eye diseases, and inform the design of display …

  2. Generalized Compressed Sensing for Image Reconstruction with Diffusion Probabilistic Models

    Publication
    We examine the problem of selecting a small set of linear measurements for reconstructing high-dimensional signals. Well-established methods for optimizing such measurements include principal component analysis …

  3. Optimal compressed sensing for image reconstruction with diffusion probabilistic models

    Publication
    We examine the problem of selecting a small set of linear measurements for reconstructing high-dimensional signals. Well-established methods for optimizing such measurements include principal component analysis …

  4. The relative contribution of color and material in object selection.

    Publication
    Object perception is inherently multidimensional: information about color, material, texture and shape all guide how we interact with objects. We developed a paradigm that quantifies how two object …

  5. A computational-observer model of spatial contrast sensitivity: Effects of wave-front-based optics, cone-mosaic structure, and inference engine

    Publication
    We present a computational-observer model of the human spatial contrast-sensitivity function based on the Image Systems Engineering Toolbox for Biology (ISETBio) simulation framework. We demonstrate that …

  6. Computational luminance constancy from naturalistic images.

    Publication
    The human visual system supports stable percepts of object color even though the light that reflects from object surfaces varies significantly with the scene illumination. To understand the …

  7. Neuronal population mechanisms of lightness perception.

    Publication
    The way that humans and animals perceive the lightness of an object depends on its physical luminance as well as its surrounding context. While neuronal responses throughout the …

  8. The perception of colour and material in naturalistic tasks.

    Publication
    Perceived object colour and material help us to select and interact with objects. Because there is no simple mapping between the pattern of an object's image on …
