The Multilayer perceptron (MLP) interpolation schemes based on the wavelet transform & subband filtering are proposed. Because estimating each sub-image signal is more effective than estimating the whole image signal, pixels in the low-resolution image are used as input signal of the MLP to estimate all of the wavelet sub-image of the corresponding high-resolution image. The image of increased resolution is finally produced by the synthesis procedure of wavelet transform. As compared with other popular methods, the results show that the improvement is remarkable. |
