Controlled growth of hexagonal GaN pyramids by hot-wall MOCVD
The growth evolution of hexagonal GaN pyramids are investigated under various growth conditions. The hexagonal GaN pyramids were grown by hot-wall metal organic chemical vapor deposition – process (hot-wall MOCVD) on a (0001) oriented GaN template. We concluded the growth of the hexagonal GaN pyramids can be divided into two different regimes defined by the adsorption kinetics of the {1101} sur...
متن کاملA Review on Multiscale Texture Features Using Steerable Pyramids
As a result of recent advancements in digital storage technology, it is now possible to create large and extensive databases of digital imagery. These collections may contain millions of images and terabytes of data. For users to make the most of these databases effective, efficient methods of searching must be devised. Having a computer do the indexing based on a CBIR scheme attempts to addres...
متن کاملFormation of ZnO hexagonal micro-pyramids: a successful control of the exposed polar surfaces with the assistance of an ionic liquid.
Wurtzite ZnO hexagonal micro-pyramids, with all exposed surfaces being polar +/- (0001) and {1011} planes, have been successfully synthesized using ionic liquids as solvents.
متن کاملIntegrated Approach for Estimation and Restoration of Photon-limited Images Based on Steerable Pyramids
In disciplines like fluorescence microscopy and astronomical imaging, the imaging process is based on detection of photons. Fluctuations in photon counting processes are described by Poisson statistics. In this paper, a new combined method based on steerable pyramids is proposed for the estimation of the degradation parameters (like noise and blur) and the restoration of photon-limited images. ...
متن کاملCurvelets, Multiresolution Representation, and Scaling Laws
Curvelets provide a new multiresolution representation with several features that set them apart from existing representations such as wavelets, multiwavelets, steerable pyramids, and so on. They are based on an anisotropic notion of scaling. The frame elements exhibit very high direction sensitivity and are highly anisotropic. In this paper we describe these properties and indicate why they ma...
