Pyramid, or pyramid representation, is a type of multi-scale signal representation developed by the computer vision, image processing and signal processing communities, in which a signal or an image is subject to repeated smoothing and subsampling. Pyramid representation is a predecessor to scale-space representation and multiresolution analysis.
The layer pyramid exhibits at one site both complex developments concerning its substructures and simplifications concerning the building methods employed for the superstructure. According to these egyptologists, the layer pyramid is a clearly advanced version of the buried pyramid of Sekhemkhet. [4] [5] [10]
A tree-pyramid (T-pyramid) is a "complete" tree; every node of the T-pyramid has four child nodes except leaf nodes; all leaves are on the same level, the level that corresponds to individual pixels in the image.
The base regularity of a pyramid's base may be classified based on the type of polygon: one example is the star pyramid in which its base is the regular star polygon. [28] The truncated pyramid is a pyramid cut off by a plane; if the truncation plane is parallel to the base of a pyramid, it is called a frustum.
Pyramid is an open source web framework written in Python and is based on WSGI.It is a minimalistic web framework inspired by Zope, Pylons and Django. [4]Originally called "repoze.bfg", Pyramid gathered attention mostly in the Zope [5] and Plone community as the Open Society Institute's KARL project migrated from Plone to BFG. [6]
The pentagonal bipyramid (or pentagonal dipyramid) is a polyhedron with ten triangular faces.It is constructed by attaching two pentagonal pyramids to each of their bases. . If the triangular faces are equilateral, the pentagonal bipyramid is an example of deltahedra, composite polyhedron, and Johnson sol

Instead of using a 4×4 grid of histogram bins, all bins extend to the center of the feature. This improves the descriptor's robustness to scale changes. The SIFT-Rank [24] descriptor was shown to improve the performance of the standard SIFT descriptor for affine feature matching. A SIFT-Rank descriptor is generated from a standard SIFT ...
