摘要： In various embodiment of the present invention, the difference of disparity between subtitles in stereoscopic content along time is restrained by a function of time and disparity. This guarantees that two consecutive subtitles will have similar disparity if they are close in time. More specifically, a method for the positioning of subtitles in stereoscopic content includes estimating a position for a subtitle in at least one frame of the stereoscopic content and restraining a difference in disparity between subtitles in at least two frames by a function of time and disparity. In such an embodiment, the estimating can include computing a disparity value for the subtitle using a disparity of an object in a region in the at least one frame in which the subtitle is to be inserted. The subtitle can then be adjusted to be in front of or behind the object.

摘要： A method and associated apparatus for using a trajectory-based technique to detect a moving object in a video sequence at incorporates human interaction through a user interface. The method comprises steps of identifying and evaluating sets of connected components in a video frame, filtering the list of connected components by comparing features of the connected components to predetermined criteria, identifying candidate trajectories across multiple frames, evaluating the candidate trajectories to determine a selected trajectory, eliminating incorrect trajectories through use of the interface and processing images in said video sequence responsive to the evaluating and eliminating steps.

摘要： A method, apparatus and system are provided for the visual inspection of a three-dimensional video stream as it is being re-encoded into a second video format. A portion of a frame of a decoded three-dimensional video stream and a corresponding portion of a frame of the three-dimensional video stream having been re-encoded are arranged into a combined video frame such that the video frame portions appear together in the combined video frame. A boundary between the video frame portions in the combined video frame is manipulated such that a change of disparity on the boundary between the video frame portions, and any overlap between the combined video frame portions, are not visible.

摘要： Methods and apparatus are provided for sampling-based super resolution video encoding and decoding. The encoding method receives high resolution pictures and generates low resolution pictures and metadata there from, the metadata for guiding post-decoding post-processing of the low resolution pictures and the metadata; and then encodes the low resolution pictures and the metadata using at least one encoder. The corresponding decoding method receives a bitstream and decodes low resolution pictures and metadata there from using a decoder; and then reconstructs high resolution pictures respectively corresponding to the low resolution pictures using the low resolution pictures and the metadata.
