Finding Objects by Grouping Primitives

Conference Record of Thirty-Second Asilomar Conference on Signals, Systems and Computers (Cat. No.98CH36284), 1999
We describe the use of a representation, called a body plan, to segment and to recognize people and animals in complex environments. The representation is an organized collection of grouping hints obtained from a combination of constraints on color and texture and constraints on geometric properties such as the structure of individual parts and the ...

On the Primitivity of the Group Algebra

Canadian Journal of Mathematics, 1971
LetGbe a group andFa field of arbitrary characteristic. In [4] Kaplansky asks under what conditions isF[G] primitive, whereF[G] is the group algebra ofGoverF. We give some necessary conditions onGthatF[G] be primitive and propose a conjecture.Definition.A ringRis primitive if it has a faithful irreducible right module.The above should really be ...

Primitive Group Treatment

Psychiatria Clinica, 2010
Although it has been known for many years that hallucinogenic drugs are used by witch doctors in the Peruvian jungles for therapeutic purposes, there have been no descriptions of their use. We studied one type of treatment carried out in groups of about 10 to 12 ‘patients’, where the healer makes a magical diagnosis and provides a potion, usually ...

On Primitive and Inner Endomorphisms of Groups

Siberian Mathematical Journal, 2020
Let \(G_r\) be a relatively free group of rank \(r\) in some variety of groups \(V\). An element \(g\in G_r\) is called primitive if it contains in some basis of \(G_r\). An endomorphism \(\phi : G_r \rightarrow G_r\) is said to preserve primitive elements or, briefly, primitive if the image \(\phi (g)\) of each primitive element \(g\) is a primitive ...

CHERYL E. PRAEGE R AN JAD N SAXLThe proble omf bounding the order of a permutation grou G ipn terms of itsdegree n was one of the central problem of 19tsh century group theory (see [4]) It.is closely relate to thde 1860 Grand Prix proble of them Pari s Academy but it, shistory goe isn fact much further back (see e.g an.
