Ad hoc Networking, Markov Random Fields, and Decision Making
DOYLE, SENAN; DOYLE, LINDA; FORDE, TIM; KOKARAM, ANIL CHRISTOPHER (2006)Our central proposition is that by articulating decision making in an ad hoc network using a Markov random field (MRF) maximum a posteriori (MAP) approach, a viable decision- making framework can be designed. This ... -
Advances in the Detection and Reconstruction of Blotches in Archived Film and Video
KOKARAM, ANIL CHRISTOPHER (IEE, 2001) -
Automated editing of medical training video via content analysis
KOKARAM, ANIL CHRISTOPHER; RING, DANIEL (SPIE, 2006)Physicians in the early part of their training inevitably undertake a course in Anatomy. Unfortunately, the amount of training medical students have with real bodies has decreased. This is further exacerbated with ... -
Automated Segmentation of Torn Frames using the Graph Cuts Technique
CORRIGAN, DAVID; HARTE, NAOMI; KOKARAM, ANIL CHRISTOPHER (2007)Film Tear is a form of degradation in archived film and is the physical ripping of the film material. Tear causes displacement of a region of the degraded frame and the loss of image data along the boundary of tear. In ... -
Automated treatment of film tear in degraded archived media
KOKARAM, ANIL CHRISTOPHER (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 ... -
Bayesian example based segmentation using a hybrid energy model
KOKARAM, ANIL CHRISTOPHER (IEEE, 2007)This paper describes a supervised segmentation algorithmwhich draws inspiration from recent advances in non-parametric texture synthesis. A set of example images which have been segmented a priori are used as a guide ... -
A Bayesian Framework for Recursive Object Removal in Movie Post-Production
KOKARAM, ANIL CHRISTOPHER (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 ... -
Browsing sports video: trends in sports-related indexing and retrieval work
KOKARAM, ANIL CHRISTOPHER (IEEE, 2006)This paper aims to identify the current trends in sports-based indexing and retrieval work. It discusses the essential building blocks for any semantic-level retrieval system and acts as a case study in content analysis ... -
Causality considerations for missing data reconstruction in image sequences
KOKARAM, ANIL CHRISTOPHER (IEEE, 1997)The 3D autoregressive (AR) model with a non-causal support region has been successfully employed in the reconstruction of texture and missing regions in image sequences. This paper discusses the causality considerations ... -
Classification and representation of semantic content in broadcast tennis videos
KOKARAM, ANIL CHRISTOPHER (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 ... -
A Comparative Error Analysis of Audio-Visual Source Localization
BOLAND, FRANCIS MORGAN; PITIE, FRANCOIS; KOKARAM, ANIL CHRISTOPHER (2008)This paper examines the accuracy of audio-video based localization using multiple cameras and multi-microphones. Covariance mapping theory is used to determine the accuracy of audio and video based localization. Both ... -
Detection and interpolation of replacement noise in motion picture sequences using 3D autoregressive modelling
KOKARAM, ANIL CHRISTOPHER (IEEE, 1994)Perhaps the most common distortion in degraded film or video material is the occurrence of blotches of varying colour randomly dispersed in each frame. The blotches are caused by the abrasion of the film or collection of ... -
Detection of Illegal Dumping from CCTV at Recycling Centres
RANKIN, ANDREW; BAUGH, GARY; HARTE, NAOMI; KOKARAM, ANIL CHRISTOPHER (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 ... -
Diagnosis and Treatment of Film Tear in Degraded Archived Media
KOKARAM, ANIL CHRISTOPHER (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 ... -
Electronic slide matching and enhancement of a lecture video
KOKARAM, ANIL CHRISTOPHER; PITIE, FRANCOIS (2007)This paper presents an automatic method to enhance video presentations for distance learning applications. From a material recorded by a fixed, non professional camera, the system matches the slides displayed during the ... -
Extraction of Non-Binary Blotch Mattes.
PITIE, FRANCOIS; KOKARAM, ANIL CHRISTOPHER; AHMED, MOHAMED (IEEE, 2009)Automated blotch removal is important in film restoration and typically involves a detection/interpolation step. Current algorithms model the corruption as a binary mixture between the original, clean images and an ... -
Fast high quality interpolation of missing data in image sequences using a controlled pasting scheme
KOKARAM, ANIL CHRISTOPHER (IEEE, 1999)An important topic in image restoration is interpolation of missing data in image sequences. Missing data is a result of dirt on film and of ageing processes where the film contents are replaced by data that bears little ... -
Fast Image Interpolation for Motion Estimation using Graphics Hardware,
KOKARAM, ANIL CHRISTOPHER (SPIE, 2004)Motion estimation and compensation is the key to high quality video coding. Block matching motion estimation is used in most video codecs, including MPEG-2, MPEG-4, H.263 and H.26L. Motion estimation is also a key component ... -
Fast removal of line scratches in old movies
KOKARAM, ANIL CHRISTOPHER (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 ... -
