Aliasing artifacts reduction with subband signal analysis for demosaicked images

Autor: Moon Gi Kang, Ji Yong Kwon, Sangwook Park, Min-Kyu Park

Publikováno v: Digital Signal Processing. 59:115-128

Demosaicking is a process used to estimate missing color values from the subsampled color filter array (CFA) image to reduce the cost and volume of a digital still camera. However, by sampling theory, it is known that subsampling a signal causes over

Angular oversampling with temporally offset layers on multilayer detectors in computed tomography

Autor: Martin Sjölin, Mats Danielsson

Publikováno v: Medical Physics. 43:2877-2883

Purpose: Today’s computed tomography(CT) scanners operate at an increasingly high rotation speed in order to reduce motion artifacts and to fulfill the requirements of dynamic acquisition, e.g., perfusion and cardiac imaging, with lower angular sam

A Blue Noise Pattern Sampling Methods to Prevent Aliasing

Autor: Gaoshuai Dai, Dechang Huang, Aiyun Zhan, Zhipeng Lin, Yuejin Zhang

Publikováno v: CSE/EUC (2)

The high frequency of the image pre-filtering and sampling can not be eliminated, whereby the power spectrum of the oscillation may cause aliasing, the sampling scheme proposed two standard blue noise pattern: step blue noise and single-peak blue noi

Robust audio localization with phase unwrapping

Autor: Walter Kellermann, Jürgen T. Geiger, Kainan Chen

Publikováno v: ICASSP

Most of multichannel sound source Direction Of Arrival (DOA) estimation algorithms suffer from spatial aliasing problems. The phase differences between a pair of microphones are wrapped beyond the spatial aliasing frequency. A common solution is to a

The visibility of motion artifacts in a video sequence e.g. motion blur and temporal aliasing, affects perceived motion quality. The frame rate required to render these motion artifacts imperceptible is far higher than is currently feasible or specif

Investigating motion blur and temporal aliasing from time-lapse electrical resistivity

Autor: Dale F. Rucker

Publikováno v: Journal of Applied Geophysics. 111:1-13

Geophysical monitoring through time-lapsed resistivity imaging is investigated to determine detrimental effects resulting from temporal smear. Temporal smear can be divided into motion blur and temporal aliasing, with motion blur attributed to an ext

Solving aliasing from shading with selective shader supersampling

Autor: Quirin Meyer, Gerd Suíner, Marc Stamminger, Christian Siegl

Publikováno v: Computers & Graphics. 37:955-962

Existing GPU antialiasing techniques, such as MSAA or MLAA, focus on reducing aliasing artifacts along silhouette boundaries or edges in image space. However, they neglect aliasing from shading in case of high-frequency geometric detail. This may lea
