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

open access: yesКомпьютерная 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.
