- <b>CDEF Filter</b> The constrained directional enhancement filter (CDEF)
allows the codec to apply a non-linear deringing filter along certain
(potentially oblique) directions. A primary filter is applied along the
- selected direction, whilst a secondary filter is applied at 45° to the
- primary direction. (See also \ref in_loop_cdef and (TODO REF)

- <b>Loop Restoration Filter</b> The loop restoration filter is applied after
- any prior post filtering stages. It acts on units of either 64 × 64,
- 128 × 128, or 256 × 256 pixel blocks, refered to as loop restoration units.
