Classification: CPC H | IPC H

Claim 0:
1. An apparatus, comprising:
at least one processor being configured to:
associate values with respective pixels of a current block of a picture according to a parametric model, wherein a set of possible partition configurations is defined according to said parametric model;
classify said pixels of said current block into partitions according to said associated values, wherein a first value according to said parametric model indicates that a pixel of said current block is in a first partition, a second value indicates that a pixel of said current block is in a second partition, and a value in between said first and second values indicates that a pixel of said current block is in a partial surface;
predict said current block to form a predicted block by:
predicting pixels in said first partition using a first predictor,
predicting pixels in said second partition using a second predictor, and
predicting pixels in said partial surface based on a weighted linear average of said first predictor and said second predictor, wherein said first predictor is weighted by w(x, y) and said second predictor is weighted by (1−w(x,y)) to form said weighted linear average, wherein w(x, y) is said value from said parametric model for pixel at location (x, y); and

decode said current block responsive to said predicted block.
