Abstract :
This paper presents a novel scheme for handling image boundary for a class of biorthogonal multidimensional (MD) perfect reconstruction (PR) filter banks (FB) using lifting scheme which finds important applications in image and video compression applications. An intuitive example is given to demonstrate our proposed for obtaining a nonexpansive transformation using nonseparable FB on arbitrary image shape.
