Photosensitive polyimides (PSPIs) are double-purpose polymers and are used as permanent materials or as temporary processing aids. Depending on their application, these polymers can be considered either as photopatternable heat-resistant materials having specific electrical, optical, or protection properties, or as thermostable photoresists used as high-performance masks for a subsequent localized process, and removed at the end.
Using big data and statistical modeling tools such as R cmdr, we were able to trace teen pregnancy to a seemingly unlikely cause: unemployment.This may have not been the most obvious insight to the teen pregnancy issue when we began this project, but by probing the data we were able to find this unexpected answer.Big Data, when coupled with powerful analysis tools, is of immense worth in converting raw data into powerful insights.
Nous presentons une methode permettant la mesure complete de la pose de la tete lors de captures video monoculaires. Ce procede utilise un modele de visage et de texture precis. Le modele facial, construit a partir d'une distribution de scans 3D haute resolution de visages, permet de generer des densites adaptees aux resolutions effectives. L'etape d'initialisation de la position du modele est cruciale car elle conditionne le suivi ulterieur de la pose. Nous proposons ainsi d'utiliser une metrique composite construite sur des textures extraites de trois bases de donnees differentes. L'algorithme est alors capable de suivre le visage dans de vastes plages de poses avec une grande precision. Nous proposons des sequences video de test dotees de verite-terrain de pose precise et independante (precision de 0.1 degres RMS)
Film has been a technology for moving image capture and reproduction for over 100 years—far longer than television. As a result, vast libraries and archives of material have accumulated all around the world, covering an extremely broad range of content from news footage to major feature movies, in addition to all the non-entertainment uses. Estimates vary, but probably somewhere between 1 and 2 million hours of filmed content exist in the world today. 1 In addition, new content is constantly being created. Despite the increasing inroads of video capture and digital cinematography techniques, film remains the medium of choice for most directors of full-length feature movies as well as for many directors of documentary, wildlife, TV mini-series, and other genres. This chapter covers some of the basic characteristics of film and describes the systems that may be used for transferring film material into the television medium. This process is quite complex, and the place of transfer has accordingly migrated from the broadcaster to specialized facilities houses; however, networks and stations may still maintain the necessary equipment in house for short-notice requirements such as airing library footage that exists only on film.
