摘要： Common techniques for Motion Compensated Frame Rate Conversion (MC-FRC) suffer from occlusion which, if not taken explicitly into account, causes a visually disturbing artifact known as 'halo'. To solve this artifact, these regions have to be detected prior to performing interpolation. Several techniques exist to detect occlusion in a frame, but these are based on motion vectors, which are frequently unreliable. The invention relates to a method to detect occlusion by comparing match errors, thereby offering occlusion detection even when the motion vectors are incorrect.

摘要： An apparatus and methods for processing video data are described. The invention provides a representation of video data that can be used to assess agreement between the data and a fitting model for a particular parameterization of the data. This allows the comparison of different parameterization techniques and the selection of the optimum one for continued video processing of the particular data. The representation can be utilized in intermediate form as part of a larger process or as a feedback mechanism for processing video data. When utilized in its intermediate form, the invention can be used in processes for storage, enhancement, refinement, feature extraction, compression, coding, and transmission of video data. The invention serves to extract salient information in a robust and efficient manner while addressing the problems typically associated with video data sources.

摘要： A method and a system for preprocessing game video sequences comprising frames and including a ball or puck as movable game object, for transmission of the video sequences in compressed form; in an initial search (12), frames are searched for the game object on the basis of comparisons of the frames with stored game object features; then, respective frames are compared with preceding frames, to decide on the basis of differences between consecutive frames whether a scene change (14b) has occurred or not, and in the case of a scene change, an initial search is started again; otherwise, tracking of the game object (18) is carried out by determining the positions of the game object in respective frames; at least for one frame, a dominant game playfield color is detected and is replaced by a unitary replacement color so that a playfield representation essentially consists of points of the same color; and the presence, size and/or shape of the detected game object is determined, to possibly replace the game object by an enlarged replacement game object (26).
