DOI: 10.1016/j.apm.2017.05.027
Abstract: Abstract More and more high dimensional data are widely used in many real world applications. This kind of data are obtained from different feature extractors, which represent distinct perspectives of the data. How to classify… read more here.

DOI: 10.1109/lsp.2019.2917518
Abstract: The discrete Mumford–Shah formalism has been introduced for the image denoising problem, allowing to capture both smooth behavior inside an object and sharp transitions on the boundary. In this letter, we propose first to extend… read more here.

DOI: 10.1109/tgrs.2022.3227061
Abstract: Hyperspectral images provide a rich representation of the underlying spectrum for each pixel, allowing for a pixelwise classification/segmentation into different classes. As the acquisition of labeled training data is very time-consuming, unsupervised methods become crucial… read more here.

DOI: 10.1109/tip.2019.2937040
Abstract: We propose an algorithm to efficiently compute approximate solutions of the piecewise affine Mumford-Shah model. The algorithm is based on a novel reformulation of the underlying optimization problem in terms of Taylor jets. A splitting… read more here.

DOI: 10.3934/ipi.2018056
Abstract: Electron micrography (EM) is a detection method for determining the structure of macromolecular complexes and biological specimens. However, some restrictions in the EM system, including poor signal-to-noise, limited range of tilt angles, only a sub-region… read more here.
