Abstract :
We propose a new rounding transform called the overlapping rounding transform (ORT). It is defined as a two-port input/two-port output FIR filtering system with a pair of rounding operations. The ORT is applied to develop lossless subband coding systems. The ORT approach has both a simpler representation and more possibilities for lossless subband implementation than the lifting scheme
