Motion estimation is described. A first portion of a predicted frame is obtained. The first portion is for a first predicted value. A first subset of a reference frame is obtained. The first subset is for a first reference value. Twice the first predicted value is subtracted from the first reference value. The outcome of the subtracting is multiplied by the first reference value to produce a partial result. The partial result is used for indication of a degree of difference between the first portion and the first subset. |
