Differential Area Profiles

In this paper a new feature descriptor, the differential area profile (DAP), is presented. DAPs, like the regular differential morphological profiles, are computed from some size distribution. The proposed method is based on the area metric given by regular connected area filters. Area compared to local width, i.e. the diameter of the structuring element in the corresponding set of openings by reconstruction in classical DMPs, leads to a rather different multi-scale decomposition. This is investigated here and an example on a very high resolution satellite image tile is given.
