Method and apparatus for adaptive weights for parallelogram prediction

Abstract

A method performed includes encoding a first vertex, a second vertex, and a third vertex of a first face of a polygon mesh; determining a set of adaptive weights that comprise a first weight, a second weight, and a third weight; and performing parallelogram prediction to predict a fourth vertex in a second face of the polygon mesh by applying the first weight to the first vertex, the second weight to the second vertex, and the third weigh to the third vertex, in which the first weight is less than 0.8 and greater than 0, in which the second weight is greater than −0.8 and less than 0, and in which the third weight is less than 0.9 and greater than 0.
