Abstract: Described herein is a multi-view display (based on spatial and/or temporal multiplexing) having an optimization mechanism that dynamically adjust views based upon detected state changes with respect to one or more views. The optimization mechanism determines viewing parameters (e.g., brightness and/or colors) for a view based upon a current position of the view, and/or on the multi-view display's capabilities. The state change may correspond to the view (a viewer's eye) moving towards another viewing zone, in which event new viewing parameters are determined, which may be in anticipation of entering the zone. Another state change corresponds to more views being needed than the display is capable of outputting, whereby one or more existing views are degraded, e.g., from 3D to 2D and/or from a personal video to a non-personal view. Conversely, a state change corresponding to excess capacity becoming available can result in enhancing a view to 3D and/or personal.

Abstract: A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.

Abstract: An aerial vehicle is outfitted with two or more digital cameras that may be continuously calibrated. The aerial vehicle may include one or more markings provided on portions of a frame, a control surface or another component that are within fields of view of the digital cameras. Based on an initial calibration of the digital cameras, intrinsic and extrinsic parameters of the digital cameras may be determined. Using the intrinsic and extrinsic parameters, locations of the markings may be determined. Subsequently, after the aerial vehicle has engaged in flight operations, images captured of the marking may be used to determine whether the digital cameras remain properly calibrated, and whether images captured using the imaging devices may be relied upon in determining ranges to objects or for any other purpose. A correction factor may be generated based on any differences between projections of the markings within the respective images.
