Visual information plays an important role in almost all areas of our life. Due to the vast amount of data associated with images, compression is a key technology for their digital transmission and storage. As an example, consider a single still color image of 512 × 512 pixels with 3 color components and 8 bits per sample per component resolution ...

Multispectral images are a particular class of images that require specialized coding algorithms. In multispectral images, the same spatial region is captured multiple times using different imaging modalities. These modalities often consist of measurements at different optical wavelengths (hence the name multispectral), but the same term is sometimes ...

Scanning microscopy. Supplement, 1989
The digital representation of an image requires a very large number of bits. The goal of image coding is to reduce this number, as much as possible, and reconstruct a faithful duplicate of the original picture. Early efforts in image coding, solely guided by information theory, led to a plethora of methods.

Still image coding includes compression of binary images and multiple-amplitude level (gray scale or color) images. Substantially different methods are applied for these two cases. This chapter gives a broad overview on different methods, which are in principle combinations of methods for signal decorrelation and analysis, quantization and coding ...

In comparison to other branches of astronomy, the production of sky images in the fields of X- and γ-rays is greatly hindered by the difficulty of focussing photons and the weakness of the fluxes with respect to the background counting rate. Interest has recently been shown in a class of telescopes based on multiplexing techniques for use in a range of

Classical transform based coders performed excellently in reducing statistical redundancies. However, reduction of statistical redundancies does not always correspond to the reduction of psychovisual redundancies. The removal of visually redundant information has potential advantages.

The scope of this chapter encompasses the coding of video signals, both black and white and color, to be displayed on a television screen for human viewing. Discussions of image sequences derived from radar, infrared, and acoustic sources as well as image sequence coding for automatic tracking of objects have been excluded.
