Problem Statement

Detecting and classifying objects in remote sensing images is a challenging task, since the objects’ optical signature is less discriminative  due to the small resolution. Common object detection methods in this area aim to find object locations by classifying local structures, while neglecting the larger surroundings of the object. However, from statistical perspective, it is evident that nearby objects provide a useful prior for object occurrence and shape. e.g. when a group of cars is parked in a row.

Goal

The goal of this work is to explore and examine methods that can be used to automatically exploit context for detecting objects in remote sensing images.
