Abstract
Methods for encoding and decoding video data. One method includes receiving video data, the video data composed of a plurality of image frames, each image frame including a plurality of pixels. The method includes determining, for each image frame, a rotation matrix, determining, for each image frame, at least one of a scaling factor and an offset factor, and determining, for each image frame, a reshaping function based on one or more values of each of the plurality of pixels. The method includes generating an output image for each image frame by applying the rotation matrix, the reshaping function, and the at least one of the scaling factor and the offset factor to the respective image frame. The rotation matrix is applied to each pixel of the plurality of pixels for the respective image frame before the reshaping function is applied to the respective image frame.
