Blotch and scratch removal in archived film using a semi-transparent corruption model and a ground-truth generation technique
Kokaram, Anil (2013)This paper has two main contributions. The first is a Bayesian framework for removing two common types of degradations on video known as blotches and line scratches. Most removal techniques assume complete obliteration of ... -
The Me31B DEAD-Box Helicase Localizes to Postsynaptic Foci and Regulates Expression of a CaMKII Reporter mRNA in Dendrites of Drosophila Olfactory Projection Neurons.
Kokaram, Anil; Hillebrand, Jens; Ramaswami, Mani (2010)mRNP granules at adult central synapses are postulated to regulate local mRNA translation and synapse plasticity. However, they are very poorly characterized in vivo. Here, in Drosophila olfactory synapses, we present early ... -
Objective Assessment of Perceptual Audio Quality Using ViSQOLAudio
Harte, Naomi; Kokaram, Anil (2017)Digital audio broadcasting services transmit substantial amounts of data that is encoded to minimize bandwidth whilst maximizing user quality of experience. Many large service providers continually alter codecs to improve ... -
On Parsing Visual Sequences with the Hidden Markov Model
Harte, Naomi; Lennon, Daire; Kokaram, Anil (2009)Hidden Markov Models have been employed in many vision applications to model and identify events of interest. Their useis common in applications where HMMs are used to classify previously divided ... -
Pathological Motion Detection for Robust Missing Data Treatment
Harte, Naomi; Kokaram, Anil; Corrigan, David (2008)This paper presents a new missing data detection algorithm that is robust to pathological motion (PM). PM causes clean image data to be misdiagnosed as missing data, resulting in damage to the image during restoration. The ... -
Perceived Audio Quality for Streaming Stereo Music.
Harte, Naomi; Kokaram, Anil; Hines, Andrew; Gillen, Eoin; Kelly, Damien; Skoglund, Jan (2014)Users of audio-visual streaming services expect an ever increasing quality of experience. Channel bandwidth remains a bottleneck commonly addressed with lossy compression schemes for both the video and audio streams. ... -
ViSQOLAudio: An objective audio quality metric for low bitrate codecs
Harte, Naomi; Kokaram, Anil; Hines, Andrew; Gillen, Eoin; Kelly, Damien; Skoglund, Jan (2015)Streaming services seek to optimise their use of bandwidthacross audio and visual channels to maximise the quality of experiencefor users. This letter evaluates whether objective quality metrics can pre-dict the audio ...
