Title: Superpixel edges for boundary detection

Abstract

Various embodiments presented herein relate to identifying one or more edges in a synthetic aperture radar (SAR) image comprising a plurality of superpixels. Superpixels sharing an edge (or boundary) can be identified and one or more properties of the shared superpixels can be compared to determine whether the superpixels form the same or two different features. Where the superpixels form the same feature the edge is identified as an internal edge. Where the superpixels form two different features, the edge is identified as an external edge. Based upon classification of the superpixels, the external edge can be further determined to form part of a roof, wall, etc. The superpixels can be formed from a speckle-reduced SAR image product formed from a registered stack of SAR images, which is further segmented into a plurality of superpixels. The edge identification process is applied to the SAR image comprising the superpixels and edges.

  • Creation of new edges in a network may be used as an indication of a potential attack on the network. Historical data of a frequency with which nodes in a network create and receive new edges may be analyzed. Baseline models of behavior among the edges in the network may be established based on the analysis of the historical data. A new edge that deviates from a respective baseline model by more than a predetermined threshold during a time window may be detected. The new edge may be flagged as potentially anomalous when the deviation from the respective baseline modelmore » is detected. Probabilities for both new and existing edges may be obtained for all edges in a path or other subgraph. The probabilities may then be combined to obtain a score for the path or other subgraph. A threshold may be obtained by calculating an empirical distribution of the scores under historical conditions.« less

  • This patent describes an apparatus for sea bottom deployment from a marine vessel for detecting the shear-wave velocity component of a seismic wave propagated form a marine seismic source following reflection of the seismic wave from a geologic boundary. The marine vessel including a cable for deploying the apparatus and for electrically conducting the detected shear-wave velocity component signals to the vessel. It comprises: at least one seismic velocity receiver for receiving acoustic velocity shear wave reflections and converting the reflections to electrical signals; a housing enclosing the velocity receiver external to and separated from the cable; ballast means locatedmore » for causing the housing to rest on the sea bottom and thereby acoustically couple the velocity receiver to the sea bottom; seregated, not helically aligned surface means for the housing for stabilizing the lateral position of the housing; weighted, elastically connected means for acoustically decoupling the housing from the cable; and electrical connector means.« less
