A Hopf texture is a vacuum field configuration of isovector fields which is an onto map from the space as a large three sphere to the vacuum manifold S. We construct a Hopf texture with spherically symmetric energy density and discuss the topological charge. A Hopf texture collapses, and we study the collapse process numerically. In our simulations, it is clear that a Hopf texture does not deca...

Research on temporal textures has concerned mainly modeling, synthesis and detection, but not finding changes between different temporal textures. Shot change detection, based on appearance, has received much research attention, but detection of changes between temporal textures has not been addressed sufficiently. Successive temporal textures in a video often have a similar appearance but diff...

considering numerous problems related to the old textures, sustainable development canbe mentioned as the most efficient approach to avoid consequent shortcomings. the methodology adoptedin the present paper is of analytical–descriptive type. using the mentioned method, the data werecollected through the field and documentary studies. the statistical society of present paper includesspecialists...

A fast, color-based algorithm for unknown illuminant is presented. of the object's color distribution R, G and B denote the 3 color 1: recognizing objects and textures viewed under an Objects are indexed by six numbers: the angles and the angles of the color edge distributions. If )ands of the image of an object (stretched out as vectors) then the color angular index comprises the 3 inter-band ...
