摘要： A system and method for providing motion compensation in decoding of a panoramic video. The panoramic video comprises a sequence encoded of image frames. Using inter frame prediction an image frame of a video is expressed in terms of at least one of neighboring image frames. In panoramic video image frames are mapped on a spherical viewing area. In the method the motion caused by camera movements is compensated by computing a difference between a reference frame and a current frame. The computed difference is then used when re-constructing the current frame, which may be placed to an image buffer and used as a reference frame for other frames.

摘要： A system and method for improving quality of encoding and decoding a panoramic video. The panoramic video comprises a sequence encoded of picture frames. In panoramic video picture frames are mapped on a spherical viewing area. In the method the projection center of the encoded frame is transformed before encoding. In the decoding phase the projection center is transformed back accordingly after decoding the frame.
