Design of benchmark imagery for validating facility annotation algorithms

The design of benchmark imagery for validation of image an notation algorithms is considered. Emphasis is placed on imagery that contains industrial facilities, such as chemical re fineries. An application-level facility ontology is used as a means to define salient objects in the benchmark imagery. Instrinsic and extrinsic scene factors important for comprehensive validation are listed, and variability in the benchmarks discussed. Finally, the pros and cons of three forms of bench mark imagery: real, composite and synthetic, are delineated.
