Useful pieces of information

Information fusion

• The JDL working group defined information fusion as ”an information process that associates, correlates and combines data and information from single or multiple sensors or sources to achieve refined estimates of parameters, characteristics, events and behaviors” [Llinas, J., Bowman, C., Rogova, G., Steinberg, A., Waltz, E., White, F.: Revisiting the jdl data fusion model II. Information Fusion, 1218–1230 (2004)], cited in Kludas08

Annotations

• Psychologists have postulated that humans are able to categorize at least tens of thousands of objects and scenes [Biederman: Recognition of components: A theory of human image understanding. PsychR 94, 115-147, 1987.]

Data on the web

• No one knows the exact number of images on the Web, but the figure is very large and is increasing rapidly. According to TheNextWeb [33], Facebook and Flickr hosted 60 billion and 6 billion images, respectively, in 2011, in contrast to 15 billion and 4 billion in 2009.
• For example, the most popular photo-sharing site—Flickr [2013], reached 5 billion photo uploads in 2011, as well as 3 to 5 million new photos uploaded daily [Kennedy et al. 2007]. Facebook held more than 60 billion photos shared by its communities as of 2011 [Facebook 2013],whereas YouTube streams more than 1 billion videos per day world- wide [YouTube 2013].

MUFIN aplikace

• Když něco nejede: kouknout na klíčové slovo v URL: http://mufin.fi.muni.cz/<klicove_slovo>; tohle klíčové slovo hledat na andromedě v /etc/apache2/conf.d/mufin_apps.conf. Tam bude typicky něco jako http://cybela2.fi.muni.cz:8080/annotation/, takže teď jít na cybela2 do opt/apache-tomcat-6.0.18/webapps, najít správná adresář, v něm WEB-INF/web.xml, tam je cesta ke konfiguračnímu xml. Pokud není celá cesta, ale jen <param-value>/image_annotation.xml</param-value>, tak je hledané xml v WEB-INF/classes. V xml se dozvím, který port na kterém stroji má běžet. Pak už jen na tom stroji vlézt do share/overlays a pustit grep cislo_portu */*.defaults a dostanu spouštěcí skript pro tenhle port.
