Inverse Airborne Optical Sectioning

We present Inverse Airborne Optical Sectioning (IAOS), an optical analogy to Synthetic Aperture Radar (ISAR). Moving targets, such as walking people, that are heavily occluded by vegetation can be made visible and tracked with a stationary sensor (e.g., hovering camera drone above forest). introduce the principles of IAOS (i.e., inverse synthetic aperture imaging), explain how signal occluders further suppressed filtering Radon transform image integral, targets’ motion parameters estimated manually automatically. Finally, we show while tracking targets in conventional aerial images is infeasible, it becomes efficiently possible integral result from IAOS.
