Using Iterated Rational Filter Banks Within the ARSIS Concept for Producing 10 m Landsat Multispectral Images

The ARSIS concept is designed to increase the spatial resolution of an image without modification of its spectral contents, by merging structures extracted from a higher resolution image of the same scene, but in a different spectral band. It makes use of ...

Coding Theory and Bilinear Complexity

Mohammad Amin Shokrollahi

The book gives an easy introduction into the theory of algebraic curves over finite fields to the extent necessary for the basic definitions of the theory of codes from algebraic geometry. Afterwards, it introduces the notion of bilinear complexity, and go ...

Optimal algorithms for multiplication in certain finite fields using elliptic curves

Mohammad Amin Shokrollahi

Using the results given in [D,. V. Chudnovsky and G. V Chudnovsky, Proc. Nat. Acad. Sci. USA, 84 (1987), pp. 1739-1743] and [W. C. Waterhouse, Ann. Sci. École Norm. Sup., 4 (1969), pp. 521560], it is proven that the rank (= bilinear complexity of multipli ...

The commutativity of up- and down-sampling in two dimensions

Martin Vetterli

The authors state and prove a theorem solving the problem of commutativity in two dimensions. It is shown under which conditions upsampling and downsampling can be interchanged in two dimensions. This is the generalization to arbitrary two-dimensional latt ...

Outline phase control for character rasterization

Roger Hersch

Character rasterization on middle-resolution output devices (screens, laser printers) is one of the most difficult tasks in the domain of resolution-independent raster imaging. Low sampling leads to unacceptable low-quality discrete character shapes. Bette ...

Vertical Scan-Conversion for Filling Purposes

Roger Hersch

Conventional scan-conversion algorithms were developed independently of filling algorithms. They cause many problems, when used for filling purposes. However, today's raster printers and plotters require extended use of filling, especially for the generati ...
