* A special volume devoted principally to therole of the late Sir Charles Oatley in the
development of the scanning electron microscopeings* It contains historical articles and …

The census transform is becoming increasingly popular in the context of optic flow
computation in image sequences. Since it is invariant under monotonically increasing grey …

We present an up-to-date survey on the topic of adaptive mathematical morphology. A broad
review of research performed within the field is provided, as well as an in-depth summary of …

In this work we introduce a formulation for a nonlocal Hessian that combines the ideas of
higher-order and nonlocal regularization for image restoration, extending the idea of …

Abstract Development of spatially-variant filtering is well established in the theory and
practice of Gaussian filtering. The aim of the paper is to study how to generalize these linear …

In this paper we are concerned with robust structure-preserving denoising filters for color
images. We build on a recently proposed transformation from the RGB color space to the …

Local M-smoothers are interesting and important signal and image processing techniques
with many connections to other methods. In our paper, we derive a family of partial …

This paper introduces mathematical morphology operators for real-valued images whose
support space is a Riemannian manifold. The starting point consists in replacing the …

Multivariate median filters have been proposed as generalizations of the well-established
median filter for gray-value images to multichannel images. As multivariate median, most of …

The performance of classifier algorithms used for predictive analytics highly dependent on
quality of training data. This requirement demands the need for noise free data or images …
