There are several different schemes. For example, one can do it using either decimation or majority rule.

The variant schemes are all forms of "block spin". The original block spin is from Kadanoff https://journals.aps.org/ppf/abstract/10.1103/PhysicsPhysiqueFizika.2.263, but I think nowadays the term refers to all variant schemes in which the underlying idea is the same.
