stelaCSF: A unified model of contrast sensitivity as the function of spatio-temporal frequency, eccentricity, luminance and area

RK Mantiuk, M Ashraf, A Chapiro - ACM Transactions on Graphics (TOG), 2022 - dl.acm.org
A contrast sensitivity function, or CSF, is a cornerstone of many visual models. It explains
whether a contrast pattern is visible to the human eye. The existing CSFs typically account …

PU21: A novel perceptually uniform encoding for adapting existing quality metrics for HDR

M Azimi - 2021 Picture Coding Symposium (PCS), 2021 - ieeexplore.ieee.org
Standard image quality metrics, such as PSNR or SSIM, cannot be directly computed on
linear high dynamic range colour values because such values non-linearly related to our …

Contrast sensitivity function in deep networks

A Akbarinia, Y Morgenstern, KR Gegenfurtner - Neural Networks, 2023 - Elsevier
The contrast sensitivity function (CSF) is a fundamental signature of the visual system that
has been measured extensively in several species. It is defined by the visibility threshold for …
