WebJul 20, 2024 · The class of quaternion matrix optimization (QMO) problems, with quaternion matrices as decision variables, has been widely used in color image processing and other engineering areas in recent years. However, optimization theory for QMO is far from adequate. The main objective of this paper is to provide necessary theoretical … WebAnalysis on Euclidean and hyperbolic spaces. On the other hand, our work gives the fundamental tools to study hyperbolic quaternion-valued signals within Quaternionic Signal Analysis. This understanding can be the basis for more generalizations of the Euclidean Quaternionic Signal Analysis. The contents of the paper are summarized in the following.
