Orientational selectivity of the human visual system [PDF]

open access: yesThe Journal of Physiology, 1966
1. It is known that an object is less detectable when it is viewed against a background containing structures similar to the object. The effect of changing the orientation between the object and background is investigated.2. Gratings of variable contrast were generated on two oscilloscopes; these were superimposed optically.

Human Visual System Model-Based Optimized Tone Mapping of High Dynamic Range Images

open access: yesIEEE Access, 2021
High dynamic range (HDR) image and video technology can provide significant picture quality improvement over the standard dynamic range (SDR). However, when HDR content is represented on an SDR display, dynamic range compression may result in image ...

The Human Visual System and Adversarial AI

open access: yesCoRR, 2020
This paper applies theories about the Human Visual System to make Adversarial AI more effective. To date, Adversarial AI has modeled perceptual distances between clean and adversarial examples of images using Lp norms. These norms have the benefit of simple mathematical description and reasonable effectiveness in approximating perceptual distance ...

Experiencing VOS: A Visual Orientation System

open access: yes, 2018
This demo introduces VOS - a Visual Orientation System. Since orientation without visual cues is challenging for humans, situations in which visibility is limited pose hindrance and sometimes a threat to human activities.
