Alexander Behrens has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10339803
    Abstract: The invention relates to a method for operating an assistance system of a motor vehicle. An image is detected by means of a camera of the assistance system and a traffic sign is determined within the detected image. An alignment of the determined traffic sign is determined with respect to the motor vehicle, and a signal device of the assistance system is triggered by the alignment.
    Type: Grant

  • Patent number: 9792511
    Abstract: A method is provided for operating a driver assistance system of a motor vehicle to detect a polygon-shaped (and especially rectangular) traffic sign with a number of edges. A camera acquires an image of the traffic sign. Within at least a portion of the image, a number of first line segments is determined, which is less than the number of edges of the traffic sign. Based on the first line segments, a reproduction of the traffic sign is identified.

  • Publication number: 20160026882
    Abstract: The invention relates to a method (20) for operating an assistance system (2) of a motor vehicle for detecting a polygon traffic sign (4) with a number of edges (14). By means of a camera (8) an image (16) of the traffic sign (4) is detected and within the detected image (16) a number of first routes (40) is determined, which is smaller than the number of edges (14) of the traffic sign (4). Based on the first routes (40) a reproduction (18) of the traffic sign (4) is identified. The invention relates further to an assistance system (2) of a motor vehicle.

  • Patent number: 8451895
    Abstract: Multiview videos are acquired of a scene with corresponding cameras arranged at poses, such that there is view overlap between any pair of cameras. V-frames are generated from the multiview videos. The V-frames are encoded using only spatial prediction. Then, the V-frames are inserted periodically in an encoded bit stream to provide random temporal access to the multiview videos. Additional view dependency information enables the decoding of a reduced number of frames prior to accessing randomly a target frame for a specified view and time, and decoding the target frame. The method also decodes multiview videos by maintaining a reference picture list for a current frame of a plurality of multiview videos, and predicting each current frame of the plurality of multiview videos according to reference pictures indexed by the associated reference picture list.

  • Patent number: 7728877
    Abstract: A system and method synthesizes multiview videos. Multiview videos are acquired of a scene with corresponding cameras arranged at a poses such that there is view overlap between any pair of cameras. A synthesized multiview video is generated from the acquired multiview videos for a virtual camera. A reference picture list is maintained for each current frame of each of the multiview videos and the synthesized video. The reference picture list indexes temporal reference pictures and spatial reference pictures of the acquired multiview videos and the synthesized reference pictures of the synthesized multiview video. Then, each current frame of the multiview videos is predicted according to reference pictures indexed by the associated reference picture list during encoding and decoding.

  • Patent number: 7489342
    Abstract: A system and method manages multiview videos. A reference picture list is maintained for each current frame of multiple multiview videos. The reference picture list indexes temporal reference pictures, spatial reference pictures and synthesized reference pictures of the multiview videos. Then, each current frame of the multiview videos is predicted according to reference pictures indexed by the associated reference picture list during encoding and decoding.
