Transfer Function Design for spl delta spl sigma converters
International Symposium on Circuits and Systems, 1994Co-Authors: S. Jantzi, C. Ouslis, Adel S. SedraAbstract:A methodology is presented for the Design of noise and signal Transfer Functions for delta-sigma modulators. A computerised optimiser is used to produce maximal noise-shaping, while meeting those constraints necessary to realise a usable modulator. The Design of higher-order modulators is possible, as is the Design of unique noise-shaping Functions such as for bandpass modulators, complex modulators, or modulators with psychoacoustically-shaped in-band noise. Optimisation of the Transfer Function from modulator input to output is also possible if special conditioning of the input signal is desired. >

topological volume skeletonization and its application to Transfer Function Design
Graphical Models \ graphical Models and Image Processing \ computer Vision Graphics and Image Processing, 2004Co-Authors: Shigeo Takahashi, Yuriko Takeshima, Issei FujishiroAbstract:Topological volume skeletonization is a novel approach for automating Transfer Function Design in visualization by extracting the topological structure of a volume dataset. The skeletonization process yields a graph called a volume skeleton tree, which consists of volumetric critical points and their connectivity. The resultant graph provides critical field values whose color and opacity are accentuated in the Design of Transfer Functions for direct volume rendering. Visually pleasing results of volume visualization demonstrate the feasibility of the present approach.

automating Transfer Function Design for comprehensible volume rendering based on 3d field topology analysis
IEEE Visualization, 1999Co-Authors: Issei Fujishiro, Taeko Azuma, Yuriko TakeshimaAbstract:This paper describes initial results of a 3D field topology analysis for automating Transfer Function Design aiming at comprehensible volume rendering. The conventional Reeb graph-based approach to describing topological features of 3D surfaces is extended to capture the topological skeleton of a volumetric field. Based on the analysis result, which is represented in the form of a hyper Reeb graph, a procedure is proposed for Designing appropriate color/opacity Transfer Functions. Two analytic volume datasets are used to preliminarily prove the feasibility of the present Design methodology.
