Abstract: A data mobility sensing method and a related apparatus are applied to the field of information technologies and storage technologies. When target structured data on a big data platform is stored, corresponding directories include a target directory, and a data mobility sensing apparatus can sense data mobility of the target directory and update a metastore on the big data platform based on the data mobility of the target directory, so that the metastore on the big data platform includes metadata of local structured data, but does not include metadata of non-local structured data.

Abstract: Various embodiments relate to a method to identify an object comprising: receiving an image, the image having an object in front of a background; segmenting the image into a segmented image using a segmentation technique, the segmented image having a foreground component showing at least a part of the object and a background component showing at least a part of the background; determining at least one property of the foreground component of the segmented image; and matching the at least one property of the foreground component with a database of identified objects having the corresponding at least one property to identify the object.

Abstract: A method and apparatus for real-time/on-line performing of multi-view multimedia applications are disclosed. In one aspect, a method of computing a disparity value of a pixel includes computing from two input images a plurality of first costs for a pixel, each cost associated with a region selected from a plurality of regions a first type, the regions covering the pixel and being substantially equal in size and shape. The method also includes computing from the first costs a plurality of second costs each associated with a region selected from a plurality of regions of a second type, the regions of the second type covering the pixel, at least some of the regions of the second type having a substantially different size and/or shape. The method further includes selecting from the second costs the minimal cost and selecting the corresponding disparity value as the disparity value.

Abstract: A system and method for motion detection and the use thereof in video coding are disclosed. In one aspect, a method of defining a region of motion within a video frame in a sequence of video frames comprises loading a current video frame and at least one reference video frame from the sequence, the reference video frame being different from the current video frame. The method further comprises applying filtering operations on the current and the reference video frame in order to obtain at least two scales of representation of the current and the reference video frame. The method further comprises determining for each of the scale representations a video-frame like representation of the structural changes between the current and the reference video frame. The method further comprises combining the video-frame like representations of different scales. The method further comprises determining one or more regions of motion from the combination.
