Abstract:
A method and apparatus related to secondary transform operations. In which, the non-zero transform coefficients in a particular subset of the transform coefficients of the block of pixels is counted and compared with a particular threshold so as to determine whether or not to perform the secondary transform on the block of pixels. Besides, the optimal secondary transform kernel size is derived implicitly based on the size of the block, or derived explicitly based on a flag coded by using an adaptive code word.

Claim (Index 12):
The method of  claim 9 , wherein a cost associated with a kernel size is computed by reconstructing residuals of the block based on NSST with the kernel size and by measuring an energy of the reconstructed residuals.
