Detection of Hedges in a Rural Landscape Using a Local Orientation Feature: From Linear Opening to Path Opening

My work on hedges detection in collaboration with Mathieu Fauvel was published in IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing. You can find the article here. This work was done at the University of Iceland in Reykjavik during my master thesis.

Two examples of results are shown below for satellite images of rural areas.

The left column shows the Normalized Difference Vegetation Index (NDVI) used to detect vegetation in satellite images. In those images, vegetation is shown in white, whereas non-vegetation areas (roads, buildings, water, etc…) are black. The right column shows in red the pixels detected as hedges by our method.
