A Critical Analysis on Perceptual Contrast and its Use in Visual Information Analysis and Processing
Beghdadi, Azeddine; Qureshi, Muhammad Ali; Amirshahi, Seyed Ali; Chetouani, Aladine; Pedersen, Marius (Peer reviewed; Journal article, 2020)Contrast in visible images is one of the most relevant characteristics of visual signals. Since the pioneering works performed in vision psychology and optics, different definitions have been proposed in the literature. ... -
High-Level Visual Masking of Image Compression Artefacts
Le Moan, Steven; Pedersen, Marius; Chetouani, Aladine (Chapter, 2020)We present the results of a subjective experiment where we measured detection thresholds for 2°wide noise targets placed in 23 different natural scenes. Unlike previous studies on visual masking, we focus particularly on ... -
Image Quality Assessment without Reference by Combining Deep Learning-Based Features and Viewing Distance
Chetouani, Aladine; Pedersen, Marius (Peer reviewed; Journal article, 2021)An abundance of objective image quality metrics have been introduced in the literature. One important essential aspect that perceived image quality is dependent on is the viewing distance from the observer to the image. ... -
On the Use of a Convolutional Neural Network to Predict Perceptual Quality of Images without Reference for Different Viewing Distances
Chetouani, Aladine; Pedersen, Marius (Chapter, 2019)A plethora of image quality metrics have been proposed in the literature. These metrics aims to estimate the perceptual image quality automatically. One important key aspect that the perceived quality is dependent on is ...
