Image/video quality assessment
Overview Video and image quality assessment Content-aware video quality assessment Color differences Methodological considerations for subjective QA studies Video and image quality assessment Quality assessment (QA) consists of measuring the user’s subjective opinion of perceived image/video quality, the user’s quality preferences, or the utility of the images for a specific task. The goal of QA is to evaluate and compare imaging systems, and to help drive system design (e.
Topics in image and video restoration at imec-IPI-Ghent University Overview High Dynamic Range imaging Denoising of time-of-flight depth images and sequences Multicamera image fusion Non-local image reconstruction Multiframe superresolution Demosaicing Error Concealment Wavelet-based denoising of images Non-local means denoising of images Restoration of historical videos Joint removal of blocking artifacts and resolution enhancement High Dynamic Range Imaging Conventional display and image capture technology is limited to a narrow range of luminosities and images associated with such systems have been retroactively called Low Dynamic Range images(LDR).

Overview Hyperspectral Image Restoration Hyperspectral Multi-sensor Data Fusion Spatial Information Modelling Image classification in hyperspectral images Hyperspectral Image Restoration Despite advances in sensor technology, hyperspectral (HS) images are inevitably degraded by noise and blur, which can affect information retrieval and content interpretation. Using denoising and deblurring as a preprocessing tool will improve various post-processing tasks, e.g. classification, target detection, unmixing, etc.
We propose a novel restoration algorithm for HS images.
test Art work project This project includes interdisciplinary work between image processing specialists, mathematicians and art scholars on virtual restoration and analysis of art work. It is conducted in collaboration with Vrije Universiteit Brussel, Department of Art, Music and Theater Sciences of Ghent University, The Flemish Academic Center for Science and Arts (VLAC) of the Royal Flemish Academy (KVAB) and the Mathematics Department, Duke University, USA. Our case study is the Ghent Altarpiece or the Lam Gods, a polyptych, dated by inscription 1432, painted by Jan and Hubert van Eyck.
