Multi-temporal remote sensing image segmentation of croplands constrained by a topographical database

In this paper we present a procedure for the segmentation of high resolution image time series of cropland areas. We use a Land Parcel Information System which gives us the parcel boundaries, but some of the parcels need to be split in several fields since they contain several crops. The procedure is based in a template matching approach which uses single crop parcels in order to generate reference signatures for the different crop classes and a similarity metric to match every pixel of the mixed parcel to the corresponding crop reference signature.
