An aerial vehicle is programmed to proceed to a safe landing area upon a loss of GPS signals or other navigational signals. The aerial vehicle is programmed with a location of the safe landing area, and a visual descriptor of a landmark at the safe landing area. The landmark may be any natural or man-made structure or feature associated with the safe landing area, and the visual identifier may be any set of data corresponding to one or more contours, outlines, colors, textures, silhouettes or shapes of the landmark. Upon determining that a GPS position may not be determined, or shortly thereafter, the aerial vehicle proceeds on a course toward the location of the safe landing area, and begins to capture imaging data. The aerial vehicle confirms that it has arrived at the safe landing area upon detecting the visual identifier within the imaging data, and initiates a landing operation.

Method for compensating illumination deficiencies in microscopic 'shape from focus (SFF)', wherein firstly the reflectance of the scene is estimated by way of a projector-camera system and then microscopic 'shape from focus (SFF)' is applied to a stack of reflectance maps rather than to the original image data.
