| Abstract: | New fast algorithms are proposed for the multidimensional type-II, -III, and
-IV discrete W transforms. Detailed procedures of decomposition are given for the twoand
three-dimensionalWtransform based on the use of odd factors in the transforms sizes.
The proposed algorithms have a regular computational structure, support various transform
lengths, and can be easily extended to higher-dimensional computations. |
