Outlier

A part of the image that is moving independently of the dominant motion

Cost

Cost factors are relative weightings used when assessing and applying different classes
of candidate MVs


The following menu items can be changed:

Robust SAD threshold
Coring level for pixel noise filtering. Adjust this to improve robustness of MV detection especially when
images are complex.

SAD Cost Factor
Default cost weighting

Temporal/Spacial Balance
Cost balance between matching motion vectors to the previous set of MVs or matching to neighbours in
the current set.

PPC Cost Threshold
PPC selection threshold after applying appropriate cost factors.

PPC MV Smooth Threshold
Level of smoothing of flow of MVs by comparison with neighbouring blocks.

PPC Selection Threshold
Used when separating MVs from noise.

BG/FG Balance Cost
BG MVs should be similar to neighbouring MVs. FG MVs are independent.

Huge Motion Distance Threshold
Threshold to limit confusion between genuine fast motion of an object or false matching with nearby
features that are similar.

Huge Motion Fallback Gain
Sensitivity coefficient for huge motion check.

MV Outlier Threshold
Validation error threshold for outlier MVs. Higher value means more likely to make a false MV between
features that are similar but unrelated.
