This paper introduces a class of linear phase lapped biorthogonal transforms with basis functions of variable length (VLGLBT). The transform can be characterized by a lattice which structurally enforces both linear phase and perfect reconstruction properties as well as provides a fast and efficient transform implementation. Our main motivation of the new transform is its application in image coding. The VLGLBT has several long overlapped basis functions for representing smooth signals to avoid… CONTINUE READING
