I am beginning to work in Core Image and applying some filters. Most that I have encountered are fairly easy to understand but a few are confusing me.
As I need a mono image I came across two: CIMaximumComponent and the corresponding CIMinimumComponent. There are others too but the description of these two is pretty sparse. Can someone expand just a little so I can understand the difference? It mentions max(r,g,b) and min of the same, what is the source of r,g,b and how is the result applied?
