Detailed Description

A region of interest (often abbreviated ROI), is a selected subset of samples within a dataset identified for a particular purpose.

An ROI can be taken literally as a polygonal selection from a 2D map. In computer vision and optical character recognition, the ROI defines the borders of an object under consideration. In many applications, symbolic (textual) labels are added to a ROI, to describe its content in a compact manner.

Within an ROI may lie individual points of interest (POIs).

In this first version, the region will be represented only by polygons.
