Communications, Power and Computing Conference: WESCANEX
作者: R. Dansereau W. Kinsner Department of Electrical and Computer Engineering Signal and Data Compression Laboratory University of Manitoba Winnipeg MAN Canada
The paper presents a perceptual image representation technique based on fractal surface interpolation (FSI), This technique is motivated from the observation that images taken from the real world contain many textures... 详细信息

Canadian Conference on electrical and computer engineering (CCECE)
作者: N. Gadhok W. Kinsner Signal and Data Compression Laboratory Department of Electrical and Computer Engineering University of Manitoba Winnipeg MAN Canada
Life sustaining biomedical signal processing demands a guarantee that the results produced are accurate and precise. The separation of sources (e.g., demixing two heart signals, one from a mother, and one from a fetus... 详细信息

Conference of the North American Fuzzy Information Processing Society - NAFIPS
作者: N. Gadhok W. Kinsner Department of Electrical and Computer Engineering Signal and Data Compression Laboratory University of Manitoba Winnipeg MAN Canada
The impact of outliers on signal separation performance of an independent component analysis (ICA) algorithm is an important factor when selecting an ICA algorithm. If an ICA estimator has the property of B-robustness... 详细信息

Canadian Conference on electrical and computer engineering (CCECE)
作者: S. Dueck W. Kinsner Department of Electrical and Computer Engineering Signal and Data Compression Laboratory University of Manitoba Winnipeg MAN Canada
This paper demonstrates the feasibility of using automated netlist partitioning to improve the performance of a single FPGA run-time reconfigurable system. Run-time reconfiguration (RTR), an important model for comput... 详细信息

IEEE International Conference on Cognitive Informatics
作者: Witold Kinsner Warren Grieder Signal and Data Compression Laboratory Department of Electrical and Computer Engineering University of Manitoba Winnipeg MAN Canada
This paper describes a fast multiscale time-domain technique for the analysis of natural speech waveforms in the presence of noise. The technique is based on the variance fractal dimension trajectory algorithm that is... 详细信息

Canadian Conference on electrical and computer engineering (CCECE)
作者: J. Greenberg W. Kinsner Department of Electrical and Computer Engineering Signal and Data Compression Laboratory University of Manitoba Winnipeg MAN Canada
The goal of this work was to determine if fractal dimensions would be useful in attempting to characterize and extract emergent behaviour from cellular automata. More specifically, we sought to determine if entropy-ba... 详细信息

Canadian Conference on electrical and computer engineering (CCECE)
作者: A. Faghfouri W. Kinsner Department of Electrical and Computer Engineering Signal and Data Compression Laboratory University of Manitoba Winnipeg MAN Canada
This paper presents the implementation aspects pertinent to the computation of the multifractal singularity spectrum through wavelets, and the methods of overcoming them. Multifractals are mixtures of monofractals, an... 详细信息
