Abstract: Method and apparatus for constrained de-blocking filter are disclosed. According to one method, a current block is partitioned into a plurality of sub-blocks using SDIP (Short Distance Intra Prediction mod). A first Bs (boundary strength) for an internal block boundary of the plurality of sub-blocks is determined by setting the first Bs to a second Bs of an Intra-coded boundary block of the current block. De-blocking process is applied, using the first Bs, to reconstructed samples across the internal block boundary of the plurality of sub-blocks to generate filtered-reconstructed samples. In another method, the current block is partitioned into two sub-blocks using SBT (sub-block transform) horizontally or vertically and the first Bs (boundary strength) is determined for an internal block boundary between the two sub-blocks by setting the first Bs to a second Bs of a non-zero cbf (coded block flag) block of the two sub-blocks in step.

Abstract: A test apparatus checks containers (13) of plastic and produced using the blow-moulding, filling and sealing methods. The containers are filled with fluid that can contain particulate contamination deposited on the container wall when the container (13) is still and floating freely in the fluid when the container (13) is moving and/or changing position owing to the movement. The contamination can be detected by a sensor (37). By a vibration device (23), the container (13) can be oscillated at a prespecifiable excitation frequency such that the particulate contamination (47) in the fluid can be detected.

Abstract: Tracking of targets in video captured by a multi-camera surveillance system is often difficult due to incomplete camera coverage and due to the complexities associated with automated recognition in a dense and highly variable environment. The present disclosure embraces a system and method for target tracking in a multi-camera surveillance system that reduces the time required for a user to track a target by offering computer generated search results that include suggestions of candidates found in the video that match (to some degree) the target. When one of the candidates is selected by a user, the search is shifted to other cameras and continued. In this way, the target may be tracked quickly. Further, a playlist of video snippets of the target is accumulated during the search and can be played to show all captured video of the target moving about the facility.

Abstract: A method for controlling a vehicle as it travels along a road includes processing at an ECU provided image data captured by a forward viewing camera and processing at the ECU a provided output indicative of a determined geographical location of the vehicle. Responsive at least in part to processing of the provided output, a geographically-derived path of travel of the vehicle is generated. Responsive to determination of a traffic lane in which the vehicle is traveling along the road, a camera-derived path of travel of the vehicle is generated. The vehicle is controlled based on (i) the geographically-derived path of travel of the vehicle and/or (ii) the camera-derived path of travel of the vehicle. The vehicle is controlled based on diminished weight of the geographically-derived path or diminished weight of the camera-derived path when a respective reliability level is below a threshold level.

Abstract: A depth camera assembly (DCA) optimizes illumination and image capture of a local area to generate depth information of the local area. The DCA determines depth information for a first portion of the local area viewable at a first pose. The DCA is moved from the first pose to a second pose, where a second portion of the local area is viewable and overlaps with the first portion. The overlapping region is not illuminated by the DCA. A non-overlapping portion of the second portion is illuminated, captured, and depth information determined.
