Expressive con- tent description languages, such as MPEG-7, provide tools for describing the temporal decomposition of content into segments. Although the semantics of temporal decom- position are apparent, the validation of the semantics of the temporal decompositions (e.g. temporal

A large set of multimedia,metadata,formats have been used for years in diverse applications. The deployment,of these formats,in the context of the Semantic Web is, however, problematic since a framework allowing agents to directly access and process existing multimedia metadata descriptions

Semantic aspects of visual information are mainly described in full text attributes or mapped onto specialized, application specific description schemes. Result lists of queries are commonly represented by textual descriptions and single key frames. This approach is valid for

Metadata standards are crucial to enable interoperable content exchange. As manual annotation is very time consuming and expensive, many archives lack the resources to perform this task and rely on automatic extraction of time-coded metadata. These technologies have in common that they produce metadata on a fine level of granularity, e.g., per segment, frame or even regions in a frame. The EBU MIM-SCAIE working group has developed the MPEG-7 Audiovisual Description Profile (AVDP), which reduces the complexity of the overall MPEG-7 MDS schema by selecting only the subset needed for broadcasting. This paper describes this profile and some selected applications that are able to work with AVDP.

An ISO draft Standard2, ISO/WD 19751-1, Office Equipment - Appearance-based image quality standards for printers - Part 1: Overview, Procedure and Common Methods, 2004 describes the overview of this multi-part appearance-based image quality standard. One of the ISO 19751 multi-part Standard&quot;s tasks is to address the appearance-based gloss and gloss uniformity issues (in ISO 19751-2). This paper summarizes the current status and technical progress since the last two updates3, 4. In particular, we will be discussion our attempt to include 75 degree gloss (G75) objective measurement5 in differential gloss and within-page gloss uniformity. The result for a round-robin experiment involving objective measurement of differential gloss using G60 and G75 gloss measurement geometry is described. The results for two perceptual-based round-robin experiments relating to haze effect on the perception of gloss, and gloss artifacts (gloss streaks/bands, gloss graininess/mottle) are discussed.© (2005) COPYRIGHT SPIE--The International Society for Optical Engineering.
