Image filtering with 2-dimensional SDF (Superimpose Digital Filter), a development of the conventional concepts on the filtering, shows a splendid future in rapid and efficient real-time processing. It has been used recently in the reconstruction of Half-Nyquist image signals and better results Were obtained. Based on mathematical analysis this paper describes a general approach to the construction of the three kinds of SDF: the WALSH, the FOURIER and the INVERSE COSINE. The structure expressions in the 2-dimensional lowpass were derived as examples. When the size of filter templates approach infinity, the limit form of its finite cut-off is presented in this paper. The results are significant in further research and utilization of SDF.
