Scale-Space Autoencoders for Unsupervised Anomaly Segmentation in Brain MRI [PDF]

Lecture Notes in Computer Science, 2020
Brain pathologies can vary greatly in size and shape, ranging from few pixels (i.e. MS lesions) to large, space-occupying tumors. Recently proposed Autoencoder-based methods for unsupervised anomaly segmentation in brain MRI have shown promising performance, but face difficulties in modeling distributions with high fidelity, which is crucial for ...

Multiresolution segmentation of natural images: from linear to nonlinear scale-space representations [PDF]

IEEE Transactions on Image Processing, 2004
In this paper, we introduce a framework that merges classical ideas borrowed from scale-space and multiresolution segmentation with nonlinear partial differential equations. A non-linear scale-space stack is constructed by means of an appropriate diffusion equation.

Colour Morphological Scale-Spaces for Image Segmentation [PDF]

Procedings of the British Machine Vision Conference 2005, 2005
Morphological scale-spaces have become an important tool for analysing greyscale images. However, their extension to colour images has proven elusive until recently. In this paper an original evaluation of two recently proposed colour sieves is presented, both algorithmically and in terms of their computational and segmentation performance.

Scale Space Operators on Hierarchies of Segmentations [PDF]

, 2013
A hierarchy of segmentations(partitions) is a multiscale set representation of the image. This paper introduces a new set of scale space operators or transformations on the space of hierarchies of partitions. An ordering of hierarchies is proposed which is endowed by an ω-ordering based on a global energy over the classes of the hierarchy.
