This paper deals with a universal coding problem for a certain kind of
multiterminal source coding network called a generalized complementary delivery
network. In this network, messages from multiple correlated sources are jointly
encoded, and each decoder has access to some of the messages to enable it to
reproduce the other messages. Both fixed-to-fixed length and fixed-to-variable
lengt...

This paper presents a new method for a quick similarity-based search through
long unlabeled audio streams to detect and locate audio clips provided by
users. The method involves feature-dimension reduction based on a piecewise
linear representation of a sequential feature trajectory extracted from a long
audio stream. Two techniques enable us to obtain a piecewise linear
representation: th...
A multiterminal lossy coding problem, which includes various problems such as
the Wyner-Ziv problem and the complementary delivery problem as special cases,
is considered. It is shown that any point in the achievable rate-distortion
region can be attained even if the source statistics are not known.
Recent studies in the field of human vision science suggest that the human
responses to the stimuli on a visual display are non-deterministic. People may
attend to different locations on the same visual input at the same time. Based
on this knowledge, we propose a new stochastic model of visual attention by
introducing a dynamic Bayesian network to predict the likelihood of where
humans typical...

This report proposes a new stochastic model of visual attention to predict the likelihood of where humans typically focus on a video scene. The proposed model is composed of a dynamic Bayesian network that simulates and combines a person's visual saliency response and eye movement patterns to estimate the most probable regions of attention. Dynamic Markov random field (MRF) models are newl...

A coding problem for correlated information sources is investigated. Messages
emitted from two correlated sources are jointly encoded, and delivered to two
decoders. Each decoder has access to one of the two messages to enable it to
reproduce the other message. The rate-distortion function for the coding
problem and its interesting properties are clarified.
This paper deals with a coding problem called complementary delivery, where
messages from two correlated sources are jointly encoded and each decoder
reproduces one of two messages using the other message as the side information.
Both lossless and lossy universal complementary delivery coding schemes are
investigated. In the lossless case, it is demonstrated that a universal
complementary deliv...
