Abstract:
1. A method for encoding a video signal having a plurality of frames including blocks each having pixels, comprising: determining, using a processor, at least a first motion field and a second motion field in a first frame, each of the first motion field and the second motion field including at least two blocks having a same direction of movement as each other, the first motion field having a first field center of motion, at least one dimension defining a shape of the first motion field and a first field motion vector, and the second motion field having a second field center of motion, at least one dimension defining a shape of the second motion field and a second field motion vector, the determining including: encoding the first motion field into a bitstream by encoding the first field center of motion, the at least one dimension defining the shape of the first motion field and the first field motion vector into the bitstream; encoding the second motion field into the bitstream by encoding the second field center of motion, the at least one dimension defining the shape of the second motion field and the first field motion vector into the bitstream; associating a first overlapping block of the first frame with one of the first motion field or the second motion field; encoding each block associated with the first motion field into the bitstream without a separate motion vector; and encoding each block associated with the second motion field into the bitstream without a separate motion vector.
