Context The recent tendency in multimedia domain is the semantic video understanding by automatic video analyzing. For that purpose, it is very important to know and study the video contents; i.e. background, actions, objects and their movements to better understand their meaning. Accordingly, object properties are very important issues. One important property which can significantly facilitate the understanding of object
Intelligent electronic device for measuring speech comprehension Main issues and objectives The main goal of this project is the conception and the creation of an electronic device for measuring speech comprehension, intended for hearing aids specialists in France and abroad. Based on the human perceptive and cognitive functioning, this equipment will enable automatic assessments of hearing aids (HA), and help
Description, Indexing, Access to Sound and Ethnomusicological Documents The laboratory of Ethnology and Comparative Sociology (LESC) including the research center of ethnomusicology (CREM) and the center of teaching and research in American Indian Ethnology (EREA) as well as the laboratory of anthropolgy of National Museum of Natural History (MNHN) are dealing with the need to index the audio archives they
Constitution, indexing and enrichment of an environmental sound corpus Corpora of environmental sounds are necessary for scientific studies of human perception and also for the creation of immersive environments (simulation, virtual reality, video games, …). This project aims to provide concrete solutions for the creation, analysis, use, and adaptation of a corpus of sounds. Main issues and objectives CIESS is
Context The analysis of instrumental activities of daily life is an important tool in the early diagnosis of dementia such as Alzheimer. The IMMED project investigates tele-monitoring technologies to support doctors in the diagnostic and follow-up of the illnesses. The project aims to automatically produce indexes to facilitate the doctor’s navigation throughout the individual video recordings. Water sound recognition is
Overview Detecting when multiple harmonic sources are present is essential for structuring various type of audio content. We propose a method for detecting area with simultaneous harmonic sources using graph analysis of the tracking of the main frequencies. As our approach seems to work on choir detection, we propose to generalise our approach to identify overlapping harmonic sources using the
Context MediaEval is a benchmarking initiative focusing on the evaluation of new algorithms enabling multimedia access and retrieval. Since 2009, many tasks have been evaluated. MediaEval offers datasets to the research community related to the set of selected tasks, the list of which is updated each year. MediaEval also focuses on the ‘multi’ aspect of multimedia (speech, audio, visual content, tags, users,
Robots for perceptual Interactions Dedicated to Daily Life Environment Main issues and objectives In order to best meet his/her needs, a robotic platform designed to assist a person in a daily living context must be endowed with multiple functionalities enabling it to perceive the person and his own environment (living place, everyday objects and activities). Robust navigation in indoor environments,
The detection of unison choir is a difficult problem as the different singers aims at singing the same thing at the same time. This leads some algorithm to classify such area as monophonic. However, we can observe little divergence between the harmonics of the different singers as shown in the figure below. Example of solo and unison choir part. The
Context Based on the idea that TV series – which tend to have more and more complex plot, with numerous characters and multiple intertwined stories – are already segmented into narrative themes in post-production, we present a system able to discover the structure of an episode without a priori knowledge. The system proceeds by segmenting the episode into shots, then
