Low-parameter method for delineation of agricultural fields in satellite images based on multi-temporal MSAVI2 data

Компьютерная оптика, 2023
This paper considers an issue of delineating agricultural fields in satellite images. In this task we follow a multi-temporal data approach. We show that on such data, good quality can be achieved using a simple low-parameter method.

Transmission / transmissions

Calenda, 2023
Les réflexions des journées d’étude de l’Association française pour l’étude du textile (AFET) porteront sur la notion de transmission. La transmission engage deux types d’acteurs distincts dans une interaction dynamique : le détenteur du savoir, qui peut être une personne physique, mais aussi un lieu, une entreprise par exemple, un objet ou une ...
