    • Who Am I?

    I am a post-doctoral student at UDS (University of Strasbourg). I work with both LSIIT/PASEO and CDS (Strasbourg Observatory).

    Educational Background

    Research Interests

    Keywords: hyperspectral image analysis, segmentation, data reduction, visualization, fusion, bayesian inference

    Applications I am interested in

    • Data cube visualization is a real problem in the astronomical framework. A part of this work is to find a way to visualize multispectral image using an adapted color space. The coloured picture must summarize all the information present in the original data
    • Galaxy classification is another part of my PhD. The purpose is to find the type of galaxies within in a galaxy field (hyperspectral data cube) using a spectral and a spatial approach. This new method is applied on astronomical objects which have a spatial and a spectral resolution
    • Fusion of hyperspectral images

    Favorite Approaches & Methods

    • Visualization: HSV (Hue, Saturation, Value) space, segmentation map obtained with a Markovian algorithm (quadtree)
    • Classification: projection method with the meanshift algorithm
