Methods and apparatus of compression for pre-stitched pictures captured by multiple cameras of a panoramic video capture device are disclosed. At the encoder side, stitching information associated with a stitching process to form the pre-stitched pictures is used to encode a current block according to embodiments of the present invention, where the stitching information comprises calibration data, matching results, seam position, blending level, sensor data, or a combination thereof. In one embodiment, the stitching information corresponds to matching results associated with a projection process, and projection-based Inter prediction is used to encode the current block by projecting a reference block in a reference pre-stitched picture to coordinates of the current block. In another embodiment, the stitching information corresponds to seam information associated with seam detection, and seam-based Inter prediction is used to encode the current block by utilizing the seam information.

Method and apparatus of video compression for pre-stitched panoramic contents

A visual data processing method applied to a visual data processing system. The visual data processing method comprises: (a) detecting a gazing point position of a user on a display; and (b) performing at least one process operation to visual data according to at least one distance between at least one display location for the visual data on the display and the gazing point position.
