Automatic background knowledge selection for matching biomedical ontologies. [PDF]
PLoS ONE, 2014 Ontology matching is a growing field of research that is of critical importance for the semantic web initiative. The use of background knowledge for ontology matching is often a key factor for success, particularly in complex and lexically rich domains ...

Optimal background matching camouflage. [PDF]
Proc Biol Sci, 2017 Background matching is the most familiar and widespread camouflage strategy: avoiding detection by having a similar colour and pattern to the background. Optimizing background matching is straightforward in a homogeneous environment, or when the habitat has very distinct sub-types and there is divergent selection leading to polymorphism.

Background complexity and optimal background matching camouflage
Behavioral Ecology and Sociobiology, 2021 Camouflage through background matching is a widespread antipredator strategy in which animals blend in with their background to avoid detection. To maximise survival in a variable natural environment, animals can have colourations that either match one of the backgrounds maximally (i.e. specialist strategy) or match multiple backgrounds partially (i.e.

Disruptive coloration and background pattern matching [PDF]
Nature, 2005 Effective camouflage renders a target indistinguishable from irrelevant background objects. Two interrelated but logically distinct mechanisms for this are background pattern matching (crypsis) and disruptive coloration: in the former, the animal's colours are a random sample of the background; in the latter, bold contrasting colours on the animal's ...

Matching Unstructured Vocabularies Using a Background Ontology [PDF]
, 2006 Existing ontology matching algorithms use a combination of lexical and structural correspondence between source and target ontologies. We present a realistic case-study where both types of overlap are low: matching two unstructured lists of vocabulary used to describe patients at Intensive Care Units in two different hospitals.

Grade inflation, social background, and labour market matching [PDF]
Journal of Economic Behavior & Organization, 2008 A model is presented where workers of differing abilities and from different social backgrounds are assigned to jobs based on grades received at school. It is examined how this matching is affected if good grades are granted to some low ability students.

Background-matching and disruptive coloration, and the evolution of cryptic coloration [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2005 Cryptic prey coloration typically bears a resemblance to the habitat the prey uses. It has been suggested that coloration which visually matches a random sample of the background maximizes background matching. We studied this previously untested hypothesis, as well as another, little studied principle of concealment, disruptive coloration,

Matching the Material of Transparent Objects: The Role of Background Distortions [PDF]
i-Perception, 2016 It has been proposed that the visual system is able to estimate the refractive index of thick transparent objects from background distortions caused by them.

Matching slides to presentation videos using SIFT and scene background matching
Proceedings of the 8th ACM international workshop on Multimedia information retrieval, 2006 We present a general approach for automatically matching electronic slides to videos of corresponding presentations for use in distance learning and video proceedings of conferences. We deal with a large variety of videos, various frame compositions and color balances, arbitrary slides sequence and with dynamic cameras switching, pan, tilt and zoom. To
