Low Rank Pure Quaternion Approximation for Pure Quaternion Matrices
Low Rank Pure Quaternion Approximation for Pure Quaternion Matrices
Quaternion matrices are employed successfully in many color image processing applications. In particular, a pure quaternion matrix can be used to represent red, green, and blue channels of color images. A low-rank approximation for a pure quaternion matrix can be obtained by using the quaternion singular value decomposition. However, this …
