This paper proposes a new discrete transform called AP-Contourlet (All Phase Contourlet). Contourlet is a flexible and fixed transform for image representations of geometrical regularity. Because it has been concluded that APDCT (All Phase DCT) filter and APIDCT (All Phase IDCT) are excellent respectively in subband decomposition and image interpolation, this paper develops a novel mutliscale decomposition method based on the APDCT filter and APIDCT interpolators to replace Laplacian Pyramid at the fist step of contoulet. Experiments in denoising typical images have shown the performance of the proposed AP-contourlet is obviously superior to original contourlet both in vision and in signal to noise ratio (SNR).
