| Abstract: | A new multi-orientation interpolation algorithm which is based on the two-dimensional Eno-Haar wavelet model is presented. During the algorithm,the characterization of two dimensional wavelet transform is studied,and the interpolations have been achieved from several orientations in order to obtain the best reconstruction image. The algorithm is proved to be feasible and ascendant by algorithm analysis. |
