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 detection in radiographs
SPIE Proceedings, 2008Image blur introduced by patient motion is one of the most frequently cited reasons for image rejection in radiographic diagnostic imaging. The goal of the present work is to provide an automated method for the detection of anatomical motion blur in digital radiographic images to help improve image quality and facilitate workflow in the radiology ...

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.

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.

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

Restoration of motion blurred images
Proceedings of the 23rd Spring Conference on Computer Graphics, 2007Degradation of digital images is often caused by camera movement when a long exposition time is set. The blurred images can be enhanced by either iterative or non-iterative methods. From the non-iterative methods, Wiener reconstruction is often used. Iterative methods are slower in nature but usually better results can be achieved.

Demosaicking images with motion blur
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010In standard digital color imaging, each pixel position acquires data for only one color plane and the remaining two color planes must be inferred through a process known as demosaicking. Furthermore, the image is susceptible to blurring artifacts due to a moving camera or fast moving subject.

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.
