A lossless image coding method, known as the two-layered residual coding (TRC) scheme, is proposed in this letter. After the H.264/AVC lossy intra prediction, we propose an advanced scheme for residual coding, which consists of two residual coders in cascade. The first-layer residual coder is conducted via transform and quantization with a coarser quantization parameter. The second-layer residual coder is a bit-plane coding method. It is shown experimentally that the TRC scheme outperforms the H.264/AVC lossless intra coding with an averaged bit rate saving of about 24%.
