Signaling filters for video processing
Abstract:
Systems, methods, and computer-readable storage media for signaling filters for reference picture resampling are described. One example involves obtaining an encoded video bitstream associated with the video data, identifying a current picture and at least one reference picture from the encoded video bitstream, and identifying signaling data from the encoded video bitstream for the video data, the signaling data including a partial set of coefficient data for at least one filter. A complete set of coefficients (e.g., filter coefficients) is derived for the at least one filter from the partial set of coefficient data and characteristics of the at least one filter, and the current picture is processed using the complete set of coefficients for the at least one filter.
