摘要:
A method for generating a confidence map comprising a plurality of confidence values, each being assigned to a respective disparity value in a disparity map assigned to at least two stereo images each having a plurality of pixels, wherein a single confidence value is determined for each disparity value, and wherein for determination of the confidence value at least a first confidence value based on a match quality between a pixel or a group of pixels in the first stereo image and a corresponding pixel or a corresponding group of pixels in the second stereo image and a second confidence value based on a consistency of the corresponding disparity estimates is taken into account.
摘要:
An apparatus and a method for refining a value of a similarity measure are described. A similarity measure is assigned to a pixel or a group of pixels of a disparity map, which is assigned to at least two stereo images each having a plurality of pixels. The similarity measure constitutes an estimate for a match quality of the pixel or the group of pixels. For refinement of the value of the similarity measure, the similarity measure between a pixel or a group of pixels in a first stereo image and a corresponding pixel or a group of corresponding pixels in a second stereo image is determined. A contrast value for the pixel or the group of pixels of the first or the second stereo image is determined and the value of the similarity measure is corrected by a correction value that is a function of the determined contrast value.

Consumers of content protected multimedia data, such as e.g. commercially available video DVDS, want to take backup copies of these data, and want to be free to play the data on any suitable playback device, while content providers want to protect these data against pirate copying. The disclosed method for accessing application data from a first storage medium, e.g. CD, uses an electronic key for decoding or converting the application data. One or more content identifiers are attached to the application data or the first storage medium. The key is stored on a copy-protected separate second storage medium, e.g. RFID tag, and compared with the content identifier. Playback or format conversion of the application data is only possible when the second storage medium is available. This allows the application data to be copied, distributed or format converted, while simultaneously preserving the content rights of the data because only one copy can be used at a time.

An apparatus for reading from an optical recording medium, and more specifically to an apparatus suitable for reading from an optical recording medium having a high data density is proposed.The apparatus has: a light source for generating a first light beam; means for generating a second light beam, which has a different wavelength than the first light beam; one or more focusing means for focusing the first light beam and the second light beam onto the optical recording medium to form a first light spot and a second light spot, wherein the second light spot is larger than the first light spot and physically and/or virtually encompasses the first light spot; one or more detectors for detecting a first light beam and a second light beam reflected by the optical recording medium; and means for generating a data signal from the difference between the detected first and second reflected light beams.
