Abstract : The motivation for this proposed research is that the volume, variety, and complexity of data being collected by the intelligence, reconnaissance, and surveillance community have far exceeded traditional signal extraction procedures for anomaly detection. Knowing the proper signature (defined as an ensemble of features that correspond to a given target or activity) to extract from a signal or image is the key to all intelligence data processing. However, most signatures found relevant for one scale or resolution might lose their meaning when the resolution is changed, which is typically the case when the sensing field-of-view or area of coverage changes.
