A Bayesian Framework for Recursive Object Removal in Movie Post-Production
(IEEE, 2003)Some of the most convincing film and video effects are created in digital post-production by removing apparatus that supports or manipulates actors and objects. Wires and people, for instance, can be removed by digitally ... -

Modeling High Level Structure in Sports with Motion Driven HMMs,
(IEEE, 2004)In this paper, we investigate the retrieval of dynamic events that occur in broadcast sports footage. Dynamic events in sports are important in so far as they are related to the game semantics. Thus far, the temporal ... -
Fast removal of line scratches in old movies
(IEEE, 2004)In this paper a fast algorithm for removing line scratches in old movies is presented. It is strongly based on exploiting the defect visibility in the image. To this aim the Weber's law can be applied to coefficients of ... -
Gradient Based Dominant Motion Estimation with Integral Projections for Real Time Video Stabilisation,
(2004)This paper presents a new expression of the relationship between integral projections and motion in an image pair. The resulting new multiresolution gradient based approach is used to estimate dominant motion in image ... -
Two layer segmentation for handling pathological motion in degraded post production media
(IEEE, 2004)The paper presents a mechanism for dealing with incorrect motion estimation in degraded post production image sequences. This tends to be caused by pathological motion (a combination of motion blur, complex foreground ... -
Inlier modeling for multimedia data analysis
(2004)This paper presents a robust method to estimate the unknown standard deviation of a centred normal distribution from a mixture density. This method is applied to different signal processing problems. The first one concerns ... -
Automated treatment of film tear in degraded archived media
(IEEE, 2004)A common form of degradation in archived film is film tear. This is caused by the physical ripping of the film. Tear causes displacement of a region of the degraded frame and the loss of image data. As of yet no method of ... -
Off-line multiple object tracking using candidate selection and the viterbi algorithm
(2005)This paper presents a probabilistic framework for off-line multiple object tracking. At each timestep, a small set of deterministic candidates is generated which is guaranteed to contain the correct solution. Tracking an ... -
Non-parametric wavelet based texture synthesis
(2005)This paper presents a new algorithm for synthesising image texture. Texture synthesis is an important process in image post-production. Previous approaches can be classified as either parametric or nonparametric. Of these ... -
Threshold learning from samples drawn from the null hypothesis for the generalized likelihood ratio cusum test
(2005)Although optimality of sequential tests for the detection of a change in the parameter of a model has been widely discussed, the test parameter tuning is still an issue. In this communication, we propose a learning strategy ... -
N-dimensional probability density function transfer and its aplication to colour transfer
(2005)This article proposes an original method to estimate a continuous transformation that maps one N-dimensional distribution to another. The method is iterative, non-linear, and is shown to converge. Only 1D marginal distribution ... -
Detection of Illegal Dumping from CCTV at Recycling Centres
(2007)This paper describes initial work on a framework for automatic detection of illegal dumping from CCTV footage from recycle centres. Frames are seperated into foreground and background regions using a Bayesian approach that ... -
Classification and representation of semantic content in broadcast tennis videos
(IEEE, 2005)This paper investigates the semantic analysis of broadcast tennis footage. We consider the spatio-temporal behaviour of an object in the footage as being the embodiment of a semantic event. This object is tracked using ... -
Pathological motion detection for robust missing data treatment in degraded archived media
(2006)This paper outlines an algorithm to improve the robustness of missing data treatment to pathological motion (PM). PM can cause misdiagnosis of clean image data as missing data. The proposed algorithm uses a probabilistic ... -
Deconvolution in real time of noisy signals
(IEE, 1982)This paper presents an analysis of the constrained least squares filter and a feedback structure is derived which shows the noise cancelling properties of the filter. Using an identification algorithm, it is shown how the ... -
A Note on the Convergence Analysis of LMS Adaptive Filters with Gaussian Data
(ISI Web of Science, 1988)Necessary and sufficient conditions fur the convergence of LMS adaptive filters with Gaussian data have been established by Horowitz and Senne [3], with the recent support of Feuer and Weinstein [4]. A feature of both ... -
Watermarking digital images for copyright protection
(IEE, 1995)A watermark is all invisible mark placed on an image that can only be detected when the image is compared with the original. This mark is designed to identify both the source of a document as well as its intended recipient. ... -
Watermarking digital images for copyright protection
(IEE, 1996)A watermark is an invisible mark placed on an image that is designed to identify both the source of an image as well as its intended recipient. The authors present an overview of watermarking techniques and demonstrate a ... -
Motion model selection in tracking humans
(IET, 2006)The performance of many human tracking algorithms rely on accurate motion models. Due to the nature of human motion it is often difficult to determine the suitability of a chosen model. It is typically the case that over ...
