Abstract
A method of estimating motion by estimating motion parameters of a complex motion model using reconstructed neighboring pixels of the current block and then applying the estimated motion parameters to the coordinates of the current block to determine motion compensated in a corresponding reference block. The parameters are not transmitted to a decoder and are derived at the decoder side. The encoder only sends a 1-bit control-flag to indicate whether the derived parameters should be used.
