Take a look at the spotlightHighlight(_:_:_:)
, colorHighlight(_:_:_:)
, and blur(_:_:_:)
functions in DepthImageFilters.swift from the final project.
Each of these functions converts a CIImage
to a CGImage
to a UIImage
. You should be able to do the same using the CIImage
from the depth map to create a UIImage
that can be saved.
