On detecting jumps in time series: Nonparametric setting

Pawlak, Mirek; Rafajlowicz, Ewaryst; Steland, Ansgar - Institut für Wirtschafts- und Sozialstatistik, … - 2003

Motivated by applications in statistical quality control and signal analysis, we propose a sequential detection procedure which is designed to detect structural changes, in particular jumps, immediately. This is achieved by modifying a median filter by appropriate kernel-based jump preserving...

Wavelet domain signal deconvolution with singularity-preserving regularization

Sánchez-Ávila, C - In: Mathematics and Computers in Simulation (MATCOM) 61 (2003) 3, pp. 165-176

In this paper, we consider a wavelet based singularity-preserving regularization scheme for use in signal deconvolution problems. The inverse problem of finding solutions with singularities to discrete Fredholm integral equations of the first kind arises in many applied fields, e.g. in...

Fuzzy and rule-based image convolution

Looney, Carl G. - In: Mathematics and Computers in Simulation (MATCOM) 51 (2000) 3, pp. 209-219

processing in the spatial domain. Edge detection is a form of drastic sharpening with conversion to black and white. The approach … taken here to sharpening and edge detection, as well as smoothing and other processing is to use a ‘smart’ convolution mask … edges with the rules and then reduce to the original size to obtain better edges than by merely applying the edge detection …
