Marco Leo, Giuseppe Massimo Bernava, Pierluigi Carcagnì, Cosimo Distante
2022 Sensors  
Traditional technologies for automatic baby motion analysis leverage contact sensors.  ...  As a consequence, also markerless video-based analysis of movements in children for NDD has been rapidly expanding but, to the best of our knowledge, there is not yet a survey paper providing a broad overview  ...  An interesting part of the study determined the impact of each video's annotations on the classifier's predicted label for that video by a unified approach inherited by the game theory.  ...

Image and Signal Processing for Networked E-Health Applications

Ilias G. Maglogiannis, Kostas Karpouzis, Manolis Wallace
2006 Synthesis Lectures on Biomedical Engineering  
Batch mode refers to the every day monitoring process, where vital signs are acquired and transmitted periodically to a health-monitoring center.  ...  Other home-monitoring conditions might include preeclampsia, anorexia, lowbirth-weight infants, growth abnormalities, and arrhythmias.  ...  Real-time video transmission for diagnostic applications is clearly the most demanding. Off-line video transmission is essentially limited by the requirement to provide patient-doctor interaction.  ...

Information, information transfer, and information processing

Ulrike Hahn
2002 Behavioral and Brain Sciences  
This fact is obscured by S&K's tendencies to conflate dynamical with "distributed" as though dynamical systems approaches automatically involve control parameters in the wider environment, and to limit  ...  Not that systems for the analysis of linguistic material are unavailable to the infant, for they are, or soon will be.  ...  In the first, section R1, we consider some of the antecedents to dynamic systems (DS) in psychology, biology, anthropology, and primatology and note the key changes that have occurred in DS over the past  ...

Sequential grouping constraints on across‐channel auditory processing

Andrew J. Oxenham, Torsten Dau
2005 Journal of the Acoustical Society of America  
An essential component of an approach to addressing this question is an ocean noise/marine ecosystem monitoring system.  ...  In this paper, we attempt to quantify the performance of mode-based processing in uncertain environments, and compare this performance to more classic processing approaches.  ...  The approach treats uncertainty within a probabilistic framework, representing both the sound speed distribution and acoustic field as stochastic processes.  ...
