Some Aspects of the Fast Karhunen-Loeve Transform

A few important properties of the fast Karhunen-Loeve transform (FKLT) proposed by Jain [3] are discussed. The purpose here is to emphasize the role of the boundary conditions upon which the entire theory is based. The effects of the zero boundary conditions are also discussed. It is argued that the transform is not as efficient as it might appear when used in bit rate reduction.
