Tutorial: Extracting Agricultural Fields in Google Maps Aerial Images



I. Objective

The objective is to extract agricultural fields in aerial images. The image are taken from Google Maps.

Whiteboard capture.Result image.

II. Method

The method is based on the assumption that agricultural fields are homogeneous areas with contrasted edges with other fields.

Thus, the processing algorithm includes:

  1. Oversegmentation using watershed segmentation where seeds correspond to zero gradients.
  2. Merging of neighbour regions with close luminance values.
  3. Merging of too small regions into most inclusive ones.
