A coordinate system for hexagonal pixels
A coordinate system is described which provides a natural means for representing hexagonally-organized pixels. The coordinate system has the unusual property that its basis vectors are not orthogonal. Vector-space properties and operations are described in this coordinate system, and shown to be straightforward computations. Some image processing algorithms, including calculations of image grad...
متن کاملRanklets on hexagonal pixel lattices
Ranklets are a family of multiscale, orientation-selective rank features suitable for characterising complex patterns. On square pixel lattices, ranklets bear a strong similarity to Haar wavelets. This extends to the sensitivity to horizontal and vertical edges. We propose a generalisation of ranklets to hexagonal pixels. The sixfold rotational symmetry of the lattice translates into features t...
متن کاملLecture ACTIVE PIXEL SENSOR (APS) DESIGN- FROM PIXELS TO SYSTEMS
Since active pixel sensors (APS) are fabricated in a commonly used CMOS process, image sensors with integrated intelligence can be designed. These sensors are very useful in many scientific, commercial and consumer applications. Current state-of-the-art CMOS imagers allow integration of all functions required for timing, exposure control, color processing, image enhancement, image compression...
متن کاملComparative Study of DCT based Image Compression on Hexagonal and Conventional Square Pixel Images
Even though, the storage space and transmission bandwidth can be reduced by compression, it will reduce the image fidelity, especially when the images are compressed at lower bit rates. Discrete Cosine Transform (DCT) based compression is an effective way of compression in which good compression ratio without losing too much of information can be obtained. In this work a comparison of DCT based...
متن کاملOne thousand square pixels of canvas
The article describes the background and the detailed history of computer icons featured in graphical interfaces—complete with visual examples and short descriptions of 21 interfaces (from 1981’s Xerox Star to upcoming BeOS Zeta). There is also a breakdown of various icon properties (such as size, style or number of colours). The article ends with a quick glimpse into the future and a conclusio...
