Claim:
A method for encoding a video signal having at least one frame with a plurality of blocks including a current block, comprising: selecting a parameterized equation for predicting the current block, wherein the parameterized equation includes a polynomial expression with coefficients and variables, wherein the coefficients include the at least one parameter and at least one of the variables is set equal to the position value, and wherein the parameterized equation is selected from a set of equations including at least one of the following equations: I ( x,y )= p 0 *x*x+p 1 *x*y+p 2 *y*y+p 3 *x+p 3 *y+p 5, I ( x,y )= p 0 *x+p 1 *y+p 2, and I ( x,y )= p 0 *x*x+p 1 *x+p 2, wherein I ( x,y ) is the predicted value, x and y are the variables and p 0- p 5 are the coefficients; determining at least one parameter for use in the selected parameterized equation; generating, for at least a first pixel in the current block, a predicted pixel value using the parameterized equation, a position value for the first pixel, and the determined at least one parameter using a processor; and encoding the current block using the predicted pixel value.
