Knowledge

Concepts and theory behind the CorridorKey pipeline.

This section explains the underlying ideas: what alpha matting is, why colour space matters for compositing, how the neural network works, and what green spill is and how it is removed. It is written for compositors, technical directors, and anyone who wants to understand the tool beyond how to operate it.

For implementation details and code references, see the Developer section.
