#377 closed defect (fixed)

Intra LM mode offset equation is incorrect

Reported by: pieterkapsenberg Owned by: bbross
Priority: minor Milestone: WD6

Description

In the derivation of the linear offset "b" in LM intra mode, the CD shows the following equation (8-75):

b = ( L – ( ( a*C ) >> k1 ) + ( 1 << ( k2 − 1 ) ) ) >> k2

This is incorrect and does not match HM, L and C should be swapped:

b = ( C – ( ( a*L ) >> k1 ) + ( 1 << ( k2 − 1 ) ) ) >> k2
