Quaternary Census Transform Based on the Human Visual System for Stereo Matching
IEEE Access, 2020 The census transform is a non-parametric local transform that is widely used in stereo matching. This transform encodes the structural information of a local patch into a binary code stream representing the relative intensity ordering of the pixels ...

LOW VISION X-RAY IMAGES CONTRAST ENHANCEMENT USING WAVELET TRANSFORM AND NON-LINEAR MAPPING
Diyala Journal of Engineering Sciences, 2009 This paper proposes a new method for enhancing the contrast of medical images based on Wavelet Transform. Wavelet transforms offer an efficient representation of the signal, finely tuned to its intrinsic properties involves simple processing techniques ...

Digital image contrast assessment based on the Weibull distribution parameters
Системный анализ и прикладная информатика, 2021 The goal of the studies described in the paper is to find a quantitative assessment that maximally correlates with the subjective assessment of the contrast image quality in the absence of reference image.

Orientational selectivity of the human visual system [PDF]
The 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.

Full Reference Image Quality Assessment by Considering Intra-Block Structure and Inter-Block Texture
IEEE Access, 2020 The purpose of the image quality assessment is to evaluate image quality consistently with human's subjective evaluation. In image quality assessment, many structural features have been used to measure the quality degradation of an image.

A Seamless Image-Stitching Method Based on Human Visual Discrimination and Attention
Applied Sciences, 2020 Stitching gaps and misalignments in mosaic images can severely degrade the human visual perception of mosaic effects. Image stitching plays a key role in eliminating these unpleasant defects.

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

A Hybrid Method for Multi-Focus Image Fusion Based on Fast Discrete Curvelet Transform
IEEE Access, 2017 This paper presents a fast discrete Curvelet transform (FDCT)-based technique for multi-focus image fusion to address two problems: texture selection in FDCT domain and block effect in spatial-based fusion.

The Human Visual System and Adversarial AI
CoRR, 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 ...
