Advanced video debanding
PITIE, FRANCOIS; KOKARAM, ANIL (ACM, 2014)High efficiency video coding has made it possible to stream video over bandwidth constrained communication networks. Depending on bit rate requirements, a video encoder sacrifices some image de- tails which can then ... -
Content Controlled Image Representation for Sports Streaming
KOKARAM, ANIL; PITIE, FRANCOIS (Suvisoft, 2005)Content based analysis has traditionally been posed in the context of identifying some material in response to a user query. This paper illustrates that given a content based analysis process that can identify semantic ... -
Feature-Cut: Video Object Segmentation Through Local Feature Correspondences.
KOKARAM, ANIL; RING, DANIEL (IEEE Computer Society, 2009)Accurately segmenting objects in video is a difficult and time consuming process in modern post-production houses. Automatic systems may work for a small number of frames, but will typically fail over longer video shots. ... -
Gradient Based Dominant Motion Estimation with Integral Projections for Real Time Video Stabilisation,
KOKARAM, ANIL; PITIE, FRANCOIS (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 ... -
N-dimensional probability density function transfer and its aplication to colour transfer
KOKARAM, ANIL; PITIE, FRANCOIS; DAHYOT, ROZENN (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 ... -
Off-line multiple object tracking using candidate selection and the viterbi algorithm
KOKARAM, ANIL; PITIE, FRANCOIS (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 ... -
User-assisted reflection detection and feature point tracking
KOKARAM, ANIL; PITIE, FRANCOIS (2013)Reflections in image sequences violate the single layer model used by most current image processing techniques. As a result reflec- tions cause many techniques to fail e.g. detection, tracking, motion estimation, etc. ... -
User-assisted sparse stereo-video segmentation
KOKARAM, ANIL; PITIE, FRANCOIS (2013)User-assisted Sparse Stereo-video Segmentation Félix Raimbault, François Pitié and Anil Kokaram Sigmedia Group Dept. of Electronic and Electrical Engineering Trinity College Dublin, Ireland {raimbauf, fpitie, ... -
ViSQOL: an objective speech quality model
HARTE, NAOMI; KOKARAM, ANIL; HINES, ANDREW; KOKARAM, ANIL CHRISTOPHER; HARTE, NAOMI; HINES, ANDREW (2015)This paper presents an objective speech quality model, ViSQOL, the Virtual Speech Quality Objective Listener. It is a signal-based, full-reference, intrusive metric that models human speech quality perception using a ... -
A Viterbi tracker for local features
KOKARAM, ANIL (SPIE, 2010)The long term tracking of sparse local features in an image is important for many applications including camera calibration for stereo applications, camera or global motion estimation and people surveillance. The majority ... -
A wavelet-based Bayesian framework for 3D object segmentation in microscopy
RAMASWAMI, MANI; PAN, KANGYU; KOKARAM, ANIL; CORRIGAN, DAVID (2012)In confocal microscopy, target objects are labeled with fluorescent markers in the living specimen, and usually appear with irregular brightness in the observed images. Also, due to the existence of out-of-focus objects ...
