Inputs

O_FocusMatcher has the following inputs:

Source	A stereo pair of images. If disparity channels and occlusion masks are not embedded in the images, you need to insert an O_DisparityGenerator and an O_OcclusionDetector node after the image sequence.
Mask	An optional mask that determines where to perform the focus matching calculation.

To see a table listing the nodes or channels each Ocula node requires in its inputs, see Node Dependencies.
