In this article, we consider graph painting and introduce the Borel-de Siebenthal property. We study this property on graphs of type E. We also study its applications in Hermitian symmetric spaces and hyperbolic Kac-Moody Lie algebras.

Meshes made from 3D points are used to represent many important geoscience concepts such as the surface of the Earth (topography), rock strata (horizons) and faults. When creating complex computer models, a geoscientist may need to directly affect the shape of such a surface to bring in in line with other data. We present a method that allows a geoscientist to precisely interact with these surf...

When artists depict a mirror in a painting, it necessarily lacks the most obvious property of a mirror: as we move around the painting of the mirror, the reflections we see in it do not change. And yet representations of mirrors and other reflecting surfaces can be quite convincing in paintings. Here, we will examine the rules of reflection, the many ways that painters can break those rules wit...

We explore a novel interaction technique using forcefeedback devices for creative manipulation of 3D models that combines interactive mesh deformation with painting a deformation property map. Painting a deformation map permits the artist to easily assign different values of “malleability” to specific areas of the model in order to locally manipulate the deformation behavior during interactive ...

In this paper we develop a method for the restoration of cracks on a painting. First, we detect the local minima (they can be either cracks or painting brush strokes), by using a morphological highpass operator, called top-hat transformation. The crack filling procedure must be applied only on the cracks and not on these dark brush strokes, which are also detected. In order to separate these br...

In order to analyse paintings, specialists use many different techniques exploring different parts of the electromagnetic spectrum: near infra-red, ultra-violet, X-rays, etc. But surprisingly, the visual domain has rarely been analysed, probably because colour perception is a very complex domain, being rather difficult to analyse adequately by means of automatic techniques. Our visual sensation...

Artworks, especially painting, are the second language or visual of an artist for expressing their ideas. Therefore, through this paper, writer tried to examine a painting entitled, “The Chronicle Devotion” using Charles Sanders Peirce Semiotics approach (Icons, Indexes and Symbols). The results study show that studied is form artists representing spirit heroism legendary sacrifice originating ...
