Cartoon blur: nonphotorealistic motion blur
Proceedings Computer Graphics International 2003, 2004Motion blur is a well-established technique which prevents strobing by making fast moving objects appear blurred. In cel animation however, different methods are used and we present a new technique to emphasise the motion of cartoon objects through the application of geometry. We term the involved nonphotorealistic motion blur as 'cartoon blur'.

Motion Regularization for Matting Motion Blurred Objects
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2010This paper addresses the problem of matting motion blurred objects from a single image. Existing single image matting methods are designed to extract static objects that have fractional pixel occupancy. This arises because the physical scene object has a finer resolution than the discrete image pixel and therefore only occupies a fraction of the pixel.

Motion blur retains some information about motion, based on which motion may be recovered from blurred images. This is a difficult problem, as the situations of motion blur can be quite complicated, such as they may be space-variant, nonlinear, and local.

Proceedings of the 2014 Indian Conference on Computer Vision Graphics and Image Processing, 2014
Camouflaging an object in a photograph is normally performed with the intent of unnoticeably hiding it within a given image. In this work, we give a different dimension to this problem and raise the interesting issue of camouaging motion blur with special relevance to non-uniformly blurred images. Given a blurred photograph, we apply a suitably derived

Motion blur for motion segmentation
2013 IEEE International Conference on Image Processing, 2013In this paper, we develop a method for motion segmentation using blur kernels. A blur kernel represents the apparent motion undergone by a scene point in the image plane. When the relative motion between the camera and scene is not restricted to fronto-parallel translations, the shape of the blur kernels can vary across image points.

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

Motion blur disturbs – the influence of motion‐blurred images in photogrammetry
The Photogrammetric Record, 2014AbstractUnmanned aerial vehicles (UAVs) have become an interesting and active research topic for photogrammetry. Current research is based on images acquired by UAVs which have a high ground resolution and good spectral resolution due to low flight altitudes combined with a high‐resolution camera.

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.

Motion blurred image restoration
2013 6th International Congress on Image and Signal Processing (CISP), 2013The restoration of motion blurred images is a hot shot in the field of image processing. In this paper, The degradation model of motion blurred images is clarified, and the estimation of the PSF parameter as well as its algorithm is presented. Frequency spectrum and Radon transition are used for the length and angle calculation, then Wiener filtering ...

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.
