*Image analysis developements for plant tissues microstructure quantification*

ABSTRACT: In a context of valorisation of plant products, such as food processing or biorefinery, it is often required to better understand the relationships between experimental condition and end-usage properties: mechanical properties, sensory texture, degradability... In order to know how the cellular structure or the tissue organisation impacts the final properties, adequate quantitative methods are required. We will present several methodological developments in the quantification of the microstructure of plant products from digital images acquired at different scales. For quantifying the 3D cellular structure of cells observed at microscopic scales, a stereological approach was developed, involving local discretization of geometric features from 3D binary images using Minkowski functionals formalism, and an estimation at the scale of the organ based on the Horvitz-Thomspon principle. Image texture analysis from mathematical morphology can be used to quantify cellular structure from grey-level macroscopy images. At a larger scale, the spatial organisation of tissues within the organ was described based on tools from spatial statistics. At each quantification scale, the question of the integration of image collection is adressed through the computation of statistical cartographies of the cellular morphology.
