Schlüsselwörter: cone-shaped frequency response, field programmable gate arrays, filter design method, hardware implementation, image sequences, multidimensional wave digital filters, recursive 3D cone filter, recursive estimation, shift operators, signal size, video processing applications, video sequence, video signal processingFPGA Zusammenfassung: In this paper a realization of a recursive 3-D cone filter applicable for low cost hardware like FPGAs, for instance, is presented. Based on the filter design method proposed by Bolle, multidimensional wave digital filters are used to approximate a cone-shaped frequency response. Focus is not set on filter design but on filter implementation and problems arising in that context. In detail, the impact of signal size, chosen processing scheme and shift operators on hardware implementation is illuminated and a suitable solution is proposed. For verification, an example of a filtered video sequence showing moving objects is given. Bemerkung: CD |

3D wave digital filter implementation on a virtex2 FPGA board with external SDRAM

Schlüsselwörter: DRAM chips, external SDRAM, field programmable gate arrays, hardware architecture, LCD monitor, n-D signal processing application, synchronous dynamic random access memory, virtex2 FPGA board, wave digital filters3D spatio-temporal wave digital filter Zusammenfassung: Many n-D signal processing applications require realization in real time. We propose the realization of a 3-D spatio-temporal wave digital filter (WDF) in an FPGA. Optimization of the implemented hardware architecture includes evaluation of two different kinds of overflow handling, namely by saturation and a ldquomodulo 2rdquo type operation. The FPGA board is processing DVI signals that can be provided by usual PC hardware. The processing output is observed in real time on an LCD monitor. Bemerkung: CD |

Insufficiencies of the practical BIBO stability concept with regard to signal processing systems

Thessaloniki, Greece
Juli

Schlüsselwörter: discrete systems, Fourier transform, frequency response, impulse response, signal processing, signal processing systems, spatio-temporal signal, Stability, transfer function, transfer functionsBIBO stability Zusammenfassung: In this paper the practical BIBO stability concept introduced by Agathoklis and Bruton is analyzed with respect to its applicability in the field of signal processing applications. In the field of n-D signal processing signals are often bounded to all but one dimension like be the time-direction of a spatio-temporal signal, for instance. This property makes the use of systems which meet the conditions of practical BIBO stability, mainly known from the field of control theory, appear to be feasible. However, it can be shown hat practical stability in its original form is not sufficient in signal processing if not further conditions are supposed. This is done by comparing the 2D Fourier transform of the actually measured impulse response of exemplary systems to the frequency response expected on basis of the transfer function. Additionally, an application example is given to verify the presented observations. Bemerkung: CD |

A realization framework based on a natural state space description of discrete k-D signal processing systems
of the International Workshop on Multidimensional (nD) Systems (nDS'09)
Thessaloniki, Greece
Juli
2009
Schlüsselwörter: discrete k-D signal processing systems, natural state space description, signal processingdiscrete domain linear k-D systems, system description Zusammenfassung: The paper presents a realization framework based on a natural state space description of n-D systems with a focus on design and analysis of discrete domain linear k-D systems. While widely used models satisfy control theoretic needs, the presented description addresses design, analysis, and realization of k-D signal processing systems. It provides a system description that offers better compliance with possible hardware realizations than existing models and thus allows evaluation and consideration of many realization specific effects. Non-causal systems that may be of interest in k-D signal processing can be described as well as shift operations / delays with respect to more than one coordinate direction. Bemerkung: CD |

Schlüsselwörter: Fourier transforms, frequency response, impulse response, line-scan camera, signal processing, spatio-temporal signal, stable n-D systems, transfer function, transfer functions, transient response2D Fourier transform Zusammenfassung: In practice, n-D signal processing problems often show the property that underlying signals are unbounded with respect to only one direction, like the spatio-temporal signal of a line-scan camera, for example. Thus, the use of systems which meet the conditions of practical BIBO stability, mainly known from the field of control theory, seems to be feasible. In this paper the practical BIBO stability concept introduced by Agathoklis and Bruton [1] is analyzed with respect to its applicability in the field of signal processing applications. It is shown that practical stability in its original form is not sufficient in signal processing if not further conditions are supposed. This is done by comparing the 2D Fourier transform of the actually measured impulse response of exemplary systems to the frequency response expected on basis of the transfer function. |
