Abstract: An apparatus for generating an overview image of a plurality of images comprises a storage unit and an image processor. The storage unit stores a plurality of processed images of the overview image and is able to provide the overview image containing the plurality of processed images at their assigned positions for displaying. The image processor determines feature points of a new image and compares the determined feature points of the new image with feature points of a stored processed image to identify common feature points and to obtain 3-dimensional positions of the common feature points. Further, the image processor determines common feature points located within a predefined maximum distance of relevance to a reference plane based on the 3-dimensional positions of the common feature points to identify relevant common feature points.

Abstract: An apparatus for generating an overview image of a plurality of images includes an image preprocessor which preprocesses a new image by assigning the new image to a position in the overview image based on position information contained by meta-data of the new image. A storage unit stores a plurality of images of the overview image and provides the overview image for display. Further, the image processor receives accuracy information of the position information. The image processor determines an overlap region of the preprocessed new image and a stored image within the overview image based on the assigned positions of the preprocessed new image and of the stored image. Further, a controllable processing engine processes the preprocessed new image by re-adjusting the assigned position of the preprocessed new image based on comparing features of the overlap region of the preprocessed new image and the stored image.

Abstract: In a relay scheme, a wireless source apparatus, a wireless destination apparatus and a wireless relay apparatus cooperate for handling transmission failures by space/time diverse channels. In the case of the successful direct transmission, reduced or no additional overhead for the relay selection is incurred. Thus, for a good SNR between source and destination, the inventive protocol has similar performance as a standard approach. In the case of a transmission failure e.g., due to small scale fading, a transmission via a different communication path implementing spatial diversity via a selected relay is supported. The device is to only activate the overhearing of signals in case of weak signal quality between sender and receiver. This selection of relay devices is done by demand only. A specific protocol for the reservation of the wireless medium for the entire cooperative communication has been specified.
