Multi-sensor approach to improve optical monitoring of papaya shrinkage during drying por Udomkun, Patchimaporn, Nagle, Marcus, Argyropoulos, D., Mahayothee, B., Müller, Joachim

“…This study aimed to assess the feasibility of a multi-sensor approach for predicting shrinkage of papaya during drying using computer vision methods in combination with optical scattering analysis of light at 650 nm. The top-side area and total surface area derived from computer vision were analyzed, while the illuminated area and light intensity from optical scattering images were used to interpret photon migration in the fruit tissue. …”
