how can i use from curvelet transform to construct a dictionary of cartoon content?

hi i want to decomposition multi focus images to cartoon and texture content . i need to construct dictionary for cartoon content and texture content . for this purpose,i have to use curvelet and DCT transforms respectively.i konw that, the basic principle of Curvelet Transform is to separate an image into a set of wavelet sub-bounds, and then to analyze each sub-band by means of a local ridgelet transform , but i dont how can i use from these for construct dictionary! please help me
