Approximate convolution using DCT coefficient multipliers
DCT-domain processing, filtering, convolution, image enhancement, quantization tables We develop a method for designing DCT coefficient multipliers in order to approximate the operation of 2D convolution of an image with a given kernel. The method is easy to implement on compressed formats of DCT-based compression methods (JPEG, MPEG, H.261) by applying decoding quantization tables that are inc...
متن کاملBloch–periodic Generalized Functions
Bloch-periodicity is a generalization of the notion of periodic and antiperiodic functions with much practical relevance for engeneering science and especially condensed matter physics. In recent work we have considered this property in the setting of classical functional analysis, and also introduced the new notion of asymptotically Bloch-periodic functions. In this paper we formulate these pr...
متن کاملInterpolation by Bloch Functions
A new interpolation problem is defined for the Bloch space and some partial results are obtained. §
متن کاملCurrent Mode Multipliers and Constant Coefficient Multipliers for Radix N and modulo N Logic Arithmetic
This paper presents new structures of combinatorial and constant coefficient multipliers based on the current-mode gates – digital elements operating with constant, continuous power supply current. Current mode circuits do not perturb the analogue part of the chip integrated on the same die through the parasitic coupling across the substrate with the same strength as voltage mode circuits do. D...
متن کاملMultipliers of Hankel transformable generalized functions
Let Hμ be the Zemanian space of Hankel transformable functions, and let H′μ be its dual space. In this paper Hμ is shown to be nuclear, hence Schwartz, Montel and reflexive. The space O, also introduced by Zemanian, is completely characterized as the set of multipliers of Hμ and of H′μ. Certain topologies are considered on O, and continuity properties of the multiplication operation with respec...
