  • Energy consumption is rapidely increasing deepening the ongoing environmental crisis. Catalysis is a way to improve the energy efficiency of industrial processes. Heterogeneous catalysts, porous microstructures, are at the heart of this process. Their morphological description provides key information; correlations have been established between structural properties and performance. In some cases, traditional numerical descriptors provide insufficient information. Therefore, new digital descriptors of microstructures have to be proposed. Our different approaches, based on distance maps, focus on various concepts: percolation, accessibility, morphological tortuosity, constrictivity and heterogeneity, for binary images characterization. Some extensions are proposed for grayscale images, which increased the applicative power.

  • The analysis of wide angle sky images for solar radiation forecast at short term, t+2min, aims to assess the amount of energy produced by a photovoltaic park. Work on a sky imager on the ground patented by Reuniwatt. Implementation under Python of a data extraction program (wide angle images of the sky, humidity, ...). Analysis of all the data for the implementation of a solar radiation forecasting method at t+2min. Research and implementation of an innovative multi-region cloud segmentation method on wide angle images of the sky, to help the forecasting of the impact of clouds over solar radiation.
