Motion blur is key to delivering a sense of speed in interactive video game rendering. Further, simulating accurate camera optical exposure properties and reduction of temporal aliasing brings us closer to high quality real-time rendering productions.

Bayesian motion blur identification using blur priori
Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004This paper presents a new approach to motion blur identification based on Bayesian paradigm and maximum a posteriori (MAP) method. To represent general spatial-invariant motion blurs, especially those caused by nonuniform and nonstraight motions, a new blur model is proposed by incorporating the knowledge of blur type or partially known motion shape as

On the Processing of a Motion-Blurred Image
SIAM Journal on Applied Mathematics, 1987The problem considered here is that of reconstructing digital test patterns in dimension one, patterns which have been blurred through a smearing transform mechanism to which noise was added. The reconstruction method is a smoothed Fourier transform technique.

14.2: Visible Motion Blur: A Perceptual Metric for Display Motion Blur
SID Symposium Digest of Technical Papers, 2010Abstract We propose a perceptual metric of display motion blur that corresponds to the visibility of the artifact. It incorporates the visual sensitivity to contrast and spatial frequency, as well as masking effects.

A phenomenon called aliasing is a major problem in image synthesis. The term refers to the fact that this phenomenon occurs when a low-frequency signal appears as an “alias” of a high-frequency signal after sampling. Practically, this means that resolution in the object space is infinite when compared with resolution in the display space.
