 ## Objectives
 
-Our objective in this application is two-fold. First, we would like to assign
-a categorical value for each "pixel" of the image as a label for [geostatistical
-learning](https://www.frontiersin.org/articles/10.3389/fams.2021.689393/full)
-tasks. Second, we would like to convert the region of the image that is inside
-of the agricultural field into a polygonal area for measurements of area and
-perimeter.
