The Effect of Peripheral Contrast Sensitivity Functions on the Performance of the Foveated Wavelet Image Quality Index
Bozorgian, Aliakbar; Pedersen, Marius; Thomas, Jean-Baptiste Denis (Peer reviewed; Journal article, 2022)The Contrast Sensitivity Function (CSF) is an integral part of objective foveated image/video quality assessment metrics. In this paper, we investigate the effect of a new eccentricity-dependent CSF model on the performance ... -
Effect of various ink types on naturalness perception of 2.5D prints
Kadyrova, Altynay; Pedersen, Marius; Westland, Stephen; Weijkamp, clemens (Journal article; Peer reviewed, 2022)Naturalness perception of 2.5D prints is content dependent and varies depending on the level of elevation used for reproduction. Moreover, various factors can influence the naturalness perception of 2.5D prints such as ink ... -

Error reduction through post processing for wireless capsule endoscope video
Floor, Pål Anders; Farup, Ivar; Pedersen, Marius; Hovde, Øistein (Peer reviewed; Journal article, 2020)The wireless capsule endoscope (WCE) is a pill-sized device taking images, which are transmitting to an on-body receiver, while traveling through the digestive system. Since image data is transmitted through the human body, ... -
Evaluating clinical diversity and plausibility of synthetic capsule endoscopic images
Vats, Anuja; Pedersen, Marius; Mohammed, Ahmed Kedir; Hovde, Øistein (Peer reviewed; Journal article, 2023)Wireless Capsule Endoscopy (WCE) is being increasingly used as an alternative imaging modality for complete and non-invasive screening of the gastrointestinal tract. Although this is advantageous in reducing unnecessary ... -
Evaluation of color spaces for unsupervised and deep learning skin lesion segmentation
Osadebey, Michael; Pedersen, Marius; Waaler, Dag (Chapter, 2020)The reliability of skin cancer diagnosis is dependent on accurate lesion segmentation. The choice of a color space in most contributions on skin lesion segmentation for melanoma detection are based on qualitative rather ... -
Evaluation of image quality metrics for sharpness enhancement
Cheng, Yao; Pedersen, Marius; Chen, Guangxue (Chapter, 2017)Image quality assessment has become a meaningful research field due to the explosive growth of image processing technologies in imaging industries. It is becoming more usual to quantify the quality of an image using image ... -
