Multimedia information retrievalMultimedia information retrieval (MMIR or MIR) is a research discipline of computer science that aims at extracting semantic information from multimedia data sources. Data sources include directly perceivable media such as audio, and video, indirectly perceivable sources such as text, semantic descriptions, biosignals as well as not perceivable sources such as bioinformation, stock prices, etc. The methodology of MMIR can be organized in three groups: Methods for the summarization of media content (feature extraction).
Compression artifactA compression artifact (or artefact) is a noticeable distortion of media (including , audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired or transmitted (streamed) within the available bandwidth (known as the data rate or bit rate). If the compressor cannot store enough data in the compressed version, the result is a loss of quality, or introduction of artifacts.
Microsoft AzureMicrosoft Azure (Windows Azure jusqu’en 2014) est la plate-forme applicative en nuage de Microsoft. Son nom évoque le « cloud computing », ou informatique en nuage (l'externalisation des ressources informatiques d'une entreprise vers des datacenters distants). Il s'agit d'une offre d'hébergement (applications et données) et de services (workflow, stockage et synchronisation des données, bus de messages, contacts...). Un ensemble d'API permet d'utiliser et d'accéder à cette plate-forme et aux services associés.
