We present a granulometric study of emerged pebble beach ridges in the Fort Williams Point, Greenwich Island, Antarctic Peninsula. We studied 8 beach ridges from the shore up to 13.5 m above current sea level. The beach ridges are made of volcanic material from the surrounding relief, but also include glacially transported gneiss and granodiorite pebble and cobble. Based on granulometric distri...

Morphological granulometry has been shown to be effective in a range of texture analysis applications. We describe an extension to the standard approach which allows truly local properties of the texture to be measured at each pixel. The result is a set of texture features which are analogous to those which could be measured for individual texture primitives, if they could be isolated. We demon...

Morphological granulometries have been used successfully to discriminate textures in the context of classical featurebased classification, and more recently they have been used as observation variables for estimators in the context of random sets. This paper considers optimal linear parametric estimation of the law of a random set. It is set in a Bayesian framework in that estimation is of the ...

This paper proposed a multi-scale segmentation method for remote sensing image based on mathematical morphology. In mathematical morphological operations, opening transform can extract lighter connected components and closing transform can extract darker ones with size smaller than a given structure element in a gray image. A connected component, as an object, may have a high response to a give...

The size distribution of concrete aggregate significantly affects the quality characteristics final concrete. However, despite its large influence, only approximate knowledge about is known during mix design and production, leading to a diminished ability controlling target properties. To overcome this limitation allow precise control desired properties, we present `Granulometry Transformer', v...

We show that the MPEG-7 color structure descriptor can be particularized down to the classical color histogram. The indexing of the structuring element used in the computation of the CSD is inducing a pseudo-granulometry over the uniform colored parts of the image. We propose the extension of the CSD via the symmetrization of the morphological granulometry, yielding a two-dimensional structure ...

In this paper, we present our preliminary study on using transformation-based techniques for performing granulometry analysis. We examine specifically the problem of the particle size analysis in oil sand images. In contrast to conventional methods of size analysis, we avoid the difficult step of image segmentation and derive information about the size distribution of the particles in the image...

We investigate the use of the standard morphological texture characterisation methods, the granulometry and the variogram, in the task of texture classification. These methods are applied to both colour and greyscale texture images. We also introduce a method for minimising the effect of different illumination conditions and show that its use leads to improved classification. The classification...

A strong correlation exists between the performance of Solid Oxide Cells (SOCs), working either in fuel cell or electrolysis mode, and their electrodes microstructure. However, the basic relationships between the three-dimensional characteristics of the microstructure and the electrode properties are not still precisely understood. Thus, several studies have been recently proposed in an attempt...

AIMS Vulnerable plaques are characterized by a high macrophage content. We investigated the optical coherence tomography (OCT) capability of identifying coronary plaque macrophage presence using tissue property indexes. METHODS AND RESULTS Fifteen epicardial coronary arteries were imaged by OCT and subsequently analysed by histology. Correlating OCT-histological sections were identified and r...
