A circular, elliptical or rectangular metal tube or pipe through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined by the physical structure of the guide.
A mathematical function used in compressing images. Images compressed using wavelets are smaller than JPEG images and can be transferred and downloaded at quicker speeds. Wavelet technology can compress color images from 20:1 to 300:1, grayscale images from 10:1 to 50:1.
- wavelet compression
The lossy compression of an image by converting it into a set of mathematical expressions.
- web as a platform
Traditionally, software was developed for specific platforms, such as Windows, Linux, or Mac OS. Today, developers build Web-based applications that run on the Web, that are completely independent of the user’s actual computer operating system. One of the goals of Web 2.0 is to facilitate the use of the Web as a development platform.
