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-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,

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.

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.

Exploiting the Structure of Background Knowledge Used in Ontology Matching.
CEUR Workshop Proceedings, 2006 We investigate the use of a background knowledge ontology in ontology matching. We conducted experiments on matching two medical ontologies using a third extensive one as background knowledge, and compare the results with directly matching the two ontologies.

Articulated Human Body Parts Detection Based on Cluster Background Subtraction and Foreground Matching [PDF]
, 2013 Detecting people or other articulated objects and localizing their body parts is a challenging computer vision problem as their movement is unpredictable under circumstances of partial and full occlusions.

Cuttlefish camouflage: Blending in by matching background features [PDF]
Current Biology, 2022 Cuttlefish are masters of camouflage and show a remarkable ability to hide in plain sight. A new study reveals how these animals translate visual information about their surroundings into effective camouflage patterns.

Background knowledge in ontology matching: A survey
Semantic Web, 2022 Ontology matching is an integral part for establishing semantic interoperability. One of the main challenges within the ontology matching operation is semantic heterogeneity, i.e. modeling differences between the two ontologies that are to be integrated. The semantics within most ontologies or schemas are, however, typically incomplete because they are

Nocturnal camouflage through background matching against moonlight. [PDF]
Proc Natl Acad Sci U S ACamouflage is often considered a daytime phenomenon based on light and shade. Nocturnal camouflage can also occur, but its mechanistic basis remains unclear. Here, we analyze the conditions for background matching (BM) of avian predators against the night sky.
