Adaptive Nonlocal Signal Restoration and Enhancement Techniques for High-Dimensional Data (2015)
Abstract / truncated to 115 words
The large number of practical applications involving digital images has motivated a significant interest towards restoration solutions that improve the visual quality of the data under the presence of various acquisition and compression artifacts. Digital images are the results of an acquisition process based on the measurement of a physical quantity of interest incident upon an imaging sensor over a specified period of time. The quantity of interest depends on the targeted imaging application. Common imaging sensors measure the number of photons impinging over a dense grid of photodetectors in order to produce an image similar to what is perceived by the human visual system. Different applications focus on the part of the electromagnetic spectrum ... toggle 14 keywordsdenoising – restoration – reconstruction – deblocking – deflickering – enhancement – adaptive transforms – spectral techniques – MRI – medical imaging – thermal imaging – volumetric data – video – motion estimation
