Abstract

Systems, apparatus, and methods are described for inferring region adaptive hierarchical transform (RAHT) coefficients based on a quantity of coefficients related to a quantity of child nodes of a RAHT tree. Based on the quantity of coefficients, the indication of a prediction mode may be inferred from previously coded (encoded or decoded) neighboring RAHT nodes, or, alternatively, determined from a set of possible prediction modes or from a bitstream. The indication may be inferred from the set of possible prediction modes, for example, if the quantity of child nodes is below a threshold. The indication may be determined from the bitstream, for example, if the quantity of child nodes is above the threshold.
