Through-Foliage Tracking with Airborne Optical Sectioning

Figure 2

Airborne Optical Sectioning (AOS) captures multiple images within a synthetic aperture that, in this work, is defined by the size of a camera array. For occlusion removal, both—occluded and unoccluded rays (dashed and solid lines, respectively)—are integrated for a common target point on the ground surface or on an approximating focal plane (resulting in one pixel of the integral image).
