Remote Sensing Image Classification Using Attribute Filters Defined Over the Tree of Shapes

Abstract: Abstract-Remotely sensed images with very high spatial resolution provide a detailed representation of the surveyed scene with a geometrical resolution that at the present can be up to 30 cm (WorldView-3). A set of powerful image processing operators have been defined in the mathematical morphology framework. Among those, connected operators (e.g., attribute filters) have proven their effectiveness in processing very high resolution images. Attribute filters are based on attributes which can be efficiently imp… Show more

“…And secondly, by using only one tree of shapes to replace both min-tree and max-tree [6], the feature dimension of SDAPs is reduced to half of that of APs. Consequently, SDAPs have been proved to be more efficient than APs in many research studies [13], [19], [20].…”

“…For attribute filtering, we exploited two attributes including the area and the moment of inertia. Ten area thresholds were adopted for the Reykjavik data as proposed by several papers [20], [39], [40]. For the Pavia University data, fourteen thresholds were automatically computed according to [24].…”

“…Any other local features can be extracted to tackle more complex VHR image scenes in future work. Also, the concept of LFAPs can be applied to the extended APs [6] for hyperspectral image classification as well as to the recently proposed selfdual APs [5] which has been proved to outperform APs.…”

“…To construct the APs, three common attributes were considered including the area, the standard deviation and the moment of inertia. The threshold values were set to be similar to previous studies on the same data [5]. For classification stage, the Random Forest was employed by setting the number of trees equal to 200.…”
