MDT_MVSTMAX_COR_T
HR
R/W
0h
This is used for increasing noise robustness. Increasing this
threshold leads to more robustness to noise, but with the potential of
introducing ghosting effect. Note that this threshold is used for
motion values for EDI only, and it is in addition mdt_mv_cor_thr.
27-24
MDT_MV_COR_THR
R/W
Ch
This threshold is for the coring for motion value, mv. MDT will
become more noise robust if this value increases. But the picture
may be washed out if this value is set to high. This threshold can be
interpreted as the noise threshold for calculating motion values for all
blocks.

Spatial frequency threshold It is used for adaptive scaling of motion
values according to how busy the texture is. If the texture is flat,
motion values need to be scaled up to reflect the sensitivity of
motion values with respect to the detection error. Increasing the
thresholds will make the motion value scaling more sensitive to the
frequency of the texture.
Note: 0 <= mdt_sf_sc_thr1 <= mdt_sf_sc_thr2 <= mdt_sf_sc_thr3
