Claim 18:
19. The method of claim 16, further comprising:
determining respective nodes values for nodes of a block using prediction techniques applied to one or more ancestor nodes of respective nodes being predicted, wherein the prediction techniques are selected from a set of supported prediction techniques comprising two or more of:
not predicted, wherein a spatial location node value for a child node is coded without prediction;
a delta prediction technique, wherein a spatial location node value for a child node is predicted as a difference from a spatial location node value of the parent node;
a linear prediction technique, wherein a spatial location node value for a child node is predicted based on a relationship between the parent node and the grandparent node of the child node; or
a parallelogram prediction technique, wherein a spatial location node value for a child node is determined based on a relationship between the parent node, the grandparent node, and the great grandparent node of the child node.
