Abstract: A method and apparatus for significance map coding for 4×4 TUs (transform units) and 8×8 TUs of video data are disclosed. The method comprises receiving at least one context selection table for a first TU associated with a first color component and generating a derived context selection table for a second TU associated with a second color component from said at least one context selection table. The first TU has a first size comprising of 4×4 and 8×8. The second TU has a second size comprising of 4×4 and 8×8. The second size is different from the first size, the second color component is different from the first color component, or both the second size is different from the first size and the second color component is different from the first color component. The derived context selection table is then used for significance map processing of the second TU.

Abstract: In an approach to tracking at least one target subject in a camera network, a search is started to find a target subject on a camera within a camera network. Features are extracted from the target subject and search queries are initiated in other nearby cameras within the camera network. Search queries attempt to detect target subjects and present the finds in a ranked order. Application of aggregate searches in multiple cameras and prior search results are used to improve matching results in the camera network; propagate a search of the target subject to discover the full pathway in the camera network; and project future occurrences of the target subject in subsequent cameras in the camera network.

Abstract: This invention concerns the tracking of objects in video data for artificial vision; for instance for a bionic eye. More particularly, the invention concerns a vision enhancement apparatus for a vision-impaired user. In other aspects, the invention concerns a method for enhancing vision and software to perform the method. The image processor operates to process video data representing images of a scene. Automatically detect and track a user selected object, such as a face, in the images. And, automatically modify the video data, by reserving a user selected area of the displayed images for displaying the tracked object as a separate video tile within the scene. The separate video tile remains in the selected area despite movement of the camera relative to the scene, or movement of the user relative to the object or the scene.

Abstract: The present invention describes a method and an arrangement for coding transform coefficients in picture and/or video coders and decoders and a corresponding computer program and a corresponding computer-readable storage medium, which can particularly be employed as a novel efficient method for binary-arithmetic coding transform coefficients in the field of video coding. For this, it is suggested that, for blocks of (video) pictures containing significant transform coefficients, coding of the transform coefficients takes place in such a way that, for each block in a scan process, the positions of significant transform coefficients in the block and subsequently, in a reverse scan order—starting from the last significant transform coefficient within the block—the values (levels) of the significant transform coefficients are determined and coded.

Abstract: An image of each frame output from an image sensing device is sequentially acquired. A situation appearing in the image is recognized through recognition processing performed on the image, and, if the recognized situation is a prescribed situation, an object of a type related to the prescribed situation is detected from the image and from an image of each frame containing the image. A detection position, in the image, of each object is used to determine whether the objects come in contact with each other in a physical space.

The drive unit may drive the actuator to control a relative position between the first capture unit and the second capture unit based on the relative position compensation value.
