    The design of 2-Dimensional (2-D) recursive orthogonal wavelet based on iterated filter banks is investigated. To obtain orthogonal wavelet, we use the parallel connection of some delays and 2-D allpass filter. In this case, a pair of digital filters with orthogonal is obtained structurally and digital filters with arbitrarily orders can be designed. Furthermore a maximum number of zeros is put at aliasing frequencies in the lowpass filter to obtain regularity of the wavelet. Design examples of discrete scaling and wavelet functions are presented throughout.
