The image illustrates two different localization techniques for UAV navigation in GPS-denied environments: TERCOM (Terrain Contour Matching) on the left, which uses pre-mapped terrain data for ...

Unlike the visual system, in which images are mapped directly onto the retina and topographically projected to higher visual areas, the auditory system must compute sound location from differences in ...
