AbstractABSTRACT:- This paper introduces a proposed method for hybrid 2D wavelet transform,
and applies this method on the field of lossless image compression method. Wavelets in 2D or
higher dimensions are often generated by a decomposition scheme from 1D wavelets. There are
two decomposition schemes; the standard (rectangular) and the nonstandard (square)
decomposition. A hybrid 2D wavelet transform is a result of mixing these two decompositions in
order to improve the compression performance and compression ratio.
