MCT is composed of two-stage filter banks similar to that

of the contourlet transform (CT) [8]. The first stage filter

banks implement multiwavelet decomposition, which capture

the point singularity effectively, in contrast to the Laplacian

pyramid used in CT. The second stage filter banks are DFBs

that link the point discontinuities into linear structures. The

implementation of MCT can be concluded as follows: 1) Prefilter

the input images 2) applyMWT to the prefiltered images -MCT is composed of two-stage filter banks similar to that
