Structural features of pyrocarbon atomistic models constructed from transmission electron microscopy images

JM Leyssale, JP Da Costa, C Germain, P Weisbecker… - Carbon, 2012 - Elsevier
We report on atomistic models of laminar pyrocarbons constructed using a combination of
2D high resolution transmission electron microscopy (HRTEM) lattice fringe image analysis, …

Spectral–spatial classification of hyperspectral images using ICA and edge-preserving filter via an ensemble strategy

…, T Adalı, Y Berthoumieu, C Germain - … on Geoscience and …, 2016 - ieeexplore.ieee.org
To obtain accurate classification results of hyperspectral images, both spectral and spatial
information should be fully exploited in the classification process. In this paper, we propose a …

Seismic fault preserving diffusion

O Lavialle, S Pop, C Germain, M Donias… - Journal of Applied …, 2007 - Elsevier
This paper focuses on the denoising and enhancing of 3-D reflection seismic data. We
propose a pre-processing step based on a non-linear diffusion filtering leading to a better …

[HTML][HTML] Comparison of SIFT encoded and deep learning features for the classification and detection of Esca disease in Bordeaux vineyards

F Rançon, L Bombrun, B Keresztes, C Germain - Remote Sensing, 2018 - mdpi.com
Grapevine wood fungal diseases such as esca are among the biggest threats in vineyards
nowadays. The lack of very efficient preventive (best results using commercial products report …

Nanoscale structure and texture of highly anisotropic pyrocarbons revisited with transmission electron microscopy, image processing, neutron diffraction and atomistic …

…, JP Da Costa, M Lalanne, G Chollon, C Germain… - Carbon, 2014 - Elsevier
We present a comparative study of the structure and texture at the nanoscale of two well-known
high-textured laminar pyrocarbons (PyCs), the rough laminar (RL) and regenerative …

Generative adversarial network for pansharpening with spectral and spatial discriminators

…, JF Aujol, Y Berthoumieu, C Germain - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
The pansharpening problem amounts to fusing a high-resolution panchromatic image with
a low-resolution multispectral image so as to obtain a high-resolution multispectral image. …

Retrieval of forest stand age from SAR image texture for varying distance and orientation values of the gray level co-occurrence matrix

I Champion, C Germain, JP Da Costa… - … and Remote Sensing …, 2013 - ieeexplore.ieee.org
Data on forest variables (eg, biomass, trunk height, density) are necessary for environmental
and forest management applications. It has been shown that texture can be used instead of …

Supervised classification of very high resolution optical images using wavelet-based textural features

…, L Bombrun, V Lafon, C Germain - IEEE Transactions on …, 2016 - ieeexplore.ieee.org
In this paper, we explore the potentialities of using wavelet-based multivariate models for the
classification of very high resolution optical images. A strategy is proposed to apply these …

Delineation of vine parcels by segmentation of high resolution remote sensed images

JP Da Costa, F Michelet, C Germain, O Lavialle… - Precision …, 2007 - Springer
Field delineation is an essential preliminary step for the design of management maps for
grape production. In this paper, we propose a new algorithm for the segmentation of vine fields …

[PDF][PDF] Early estimation of vineyard yield: site specific counting of berries by using a smartphone.

M Grossetete, Y Berthoumieu, JP Costa, C Germain… - 2012 - researchgate.net
Early yield estimation needs to be more accurate in order to improve site specific management
of vineyards and increase their profitability. Common methods for yield estimation are …
