Chapter 7. Background Tasks

The Background Tasks View displays running background tasks.

ML Background Tasks is a framework to execute long taking tasks in worker threads. The basic framework is independent of the ML, but convenience classes add access to ML images. For more on background tasks, see the ToolBox Reference, chapter “Background Tasks”.
