Quaternion Filtering Based on Quaternion Involutions and its Application in Signal Processing
The quaternion gradient plays an important role in quaternion signal processing, and has undergone several modifications. Recently, three methods for obtaining the quaternion gradient have been proposed based on generalized HR calculus, the quaternion product, and quaternion involutions, respectivel...
