Abstract: A method for translating two-dimensional data of a DWT system has a stairway scan way with a border extension to translate a two-dimensional data to at least two one-dimensional data to be able to execute in the Wavelet transform. The one-dimensional data with less extension data in executing the wavelet transform not only uses small size memory but also has high transforming speed. Therefore the two-dimensional data is compressed by the wavelet transform with the boundary extension process according to the present invention has good compressed rate.
