Sentence examples for rotation operation from inspiring English sources

From linear algebra theory, every linear transformation can be represented as a composition of three operations: a rotation operation, a scaling operation, and another rotation operation [28].

The rotation operation changes the content locations, hence difficult to handle in image hashing techniques [24].

The computational complexity of the rotation operation can be greatly simplified by quantizing the angle.
