Purifying Selection, Sequence Composition, and Context-Specific Indel Mutations Shape Intraspecific Variation in a Bacterial Endosymbiont

Comparative genomics of closely related bacterial strains can clarify mutational processes and selective forces that impact genetic variation. Among primary bacterial endosymbionts of insects, such analyses have revealed ongoing genome reduction, raising questions about the ultimate evolutionary fate of these partnerships. Here, we explored genomic variation within Blochmannia vafer, an obligat...

Shape Semantics from Shape Context

3D models play an important role in many industrial applications. Therefore semantic processing for the purposes of comparing, cataloging and archiving shapes is a major concern. Most previous work considers comparisons based on the object’s overall geometry or in a reference frame which is computed from the object’s geometry alone, disregarding its context. There are also approaches which prop...

Variations in Shape Context Descriptor: A Survey

There is a great significance of Image retrieval in multimedia and for image retrieval shape is one of the promising features. This paper presents a survey on one of the method of image retrieval based on shape. First, Shape context is described in this paper and the various versions of it that are implemented are given in detail. This paper gives a summarized view of all the methods of shape c...

A modified shape context method for shape based object retrieval

The complexity in shape context method and its simplification is addressed. A novel, but simple approach to design shape context method including Fourier Transform for the object recognition is described. Relevance of shape context, an important descriptor for the recognition process is detailed. Inclusion of information regarding all the contour points (with respect to a reference point) in co...
