• ’Characterisation of the nutritional composition of Ghanaian fruits and vegetables and the impact of cooking methods’
  3 May 2021

  ’Micronutrient deficiencies are widespread in Ghana, linked to diets that are predominantly starch-based with less fruits and vegetables. Ghana produces a variety of fruit and vegetables, but little is known about these products and their nutritional importance. The aim of the project was therefore to measure the micronutrient contents in various fruit and vegetables, in order to identify the best sources and have convincing data for their recommendation, as well as evaluate the impact of (...)

• Combining opto-physical modelling of plant structures and chemometrics tools for robust calibration of hyperspectral field images; Application to plant phenotyping
  29 April 2022

  Short range hyperspectral imagery is a promising tool for phenotyping and vegetation survey. When associated with partial least square regression (PLS-R), it allows high spatial resolution mapping of the plant chemical content at the canopy scale.
  However, several optical phenomena have to be taken into account when applying this approach to vegetation scenes in natural conditions. For instance, additive and multiplicative factors due respectively to specular reflection and leaf inclination (...)
