Characterization of facets of particles is a common problem. In this paper an algorithm is presented which allows automated quantitative 3D analysis of facets of many particles within tomographic datasets. The algorithm is based on the analysis of pr

Reproduction, BioScientifica, 2010, 139 (1), pp.129-137. ⟨10.1530/REP-08-0435⟩
International audience; Efficient reprograming of the donor cell genome in nuclear transfer (NT) embryos is linked to the ability of the embryos to sustain full-term development. As the nuclear architecture has recently emerged as a key factor in the

In the mouse zygote, DNA methylation patterns undergo important changes and differ in the maternal and paternal pronucleus. Demethylation of the paternal genome has been described as an active and replication-independent process, although the mechani

Efficient N-Dimensional surface estimation using Crofton formula and run-length encoding
Autor: Gaetan Lehmann, David Legland
Publikováno v: The Insight Journal.
Unlike the measure of the area in 2D or of the volume in 3D, the perimeter and the surface are not easily measurable in a discretized image. In this article we describe a method based on the Crofton formula to measure those two parameters in a discri

Tophap by area
Autor: Gaetan Lehmann
Publikováno v: The Insight Journal.
The tophat transform is a well know and widely used transform based of morphological opening or closing. It is often used to remove the background in an image, where the background is defined as the zones which do not fit in the user provided kernel.

In eukaryotes, the interphase nucleus is organized in morphologically and/or functionally distinct nuclear “compartments”. Numerous studies highlight functional relationships between the spatial organization of the nucleus and gene regulation. Th
