Global Detection and Repair
The Global Detection UI has the following parameter controls:
To:Use:
calculate forward and backward motion vectors.Calculate Motion
control the quality of the motion vectors by applying the motion
analysis only to lower-resolution versions of the input image, up
to the resolution specified by the quality parameter.
Quality
determine how many pixels are classified as dust. If the Tolerance
is set to 0, then no dust is detected, effectively disabling the dust
Tolerance
detection. If a dust channel from a film scanner is applied, the
Tolerance can be set to 0 to avoid dust detection. Otherwise, the
dust channel will be the union of the scanner matte and the de-
tected matte. If the Tolerance is set to 100, then all pixels are
dust. A value of 100 might be used with a shape to label all pixels
within a small region as dust.
control into which regions the dust is expanded. A value less than
or equal to Tolerance means do not expand.
Size Tolerance
control how expanded the detected dust is expanded. A value of
0 means do not expand.
Size
control the smoothing effect on the first step of dust detection
where every pixel is assigned a likelihood of being dust.
Detection Radius
remove false dust in areas of motion, as its value is raised.Motion Threshold
The Global Correction UI has the following parameter controls:
