Iterative energy-based projection on a normal data manifold for anomaly localization

1 code implementation ICLR 2020 David Dehaene, Oriel Frigo, Sébastien Combrexelle, Pierre Eline

Indeed, an autoencoder trained on normal data is expected to only be able to reconstruct normal features of the data, allowing the segmentation of anomalous pixels in an image via a simple comparison between the image and its autoencoder reconstruction.

Bayesian estimation of the multifractality parameter for image texture using a Whittle approximation

no code implementations17 Oct 2014 Sébastien Combrexelle, Herwig Wendt, Nicolas Dobigeon, Jean-Yves Tourneret, Steve McLaughlin, Patrice Abry

Multifractal analysis is a useful signal and image processing tool, yet, the accurate estimation of multifractal parameters for image texture remains a challenge.
