More Information
Summary:The invention provides an image super-resolution processing method. The method comprises the steps of conducting wavelet transformation on an image sequence to be magnified to obtain sub-band images which respectively comprise a low-frequency sub-band, a horizontal high-frequency sub-band, a perpendicular high-frequency sub-band and a diagonal line high-frequency sub-band; conducting super-resolution reconstruction processing on the image sequence to be magnified so as to obtain a super-resolution image; respectively conducting interpolation on components of the horizontal high-frequency sub-band, components of the perpendicular high-frequency sub-band and components of the diagonal line high-frequency sub-band to obtain corresponding interpolation images; conducting the wavelet inverse transformation on the super-resolution image and the interpolation images to obtain the magnified image. The invention further provides a corresponding system, the low-resolution image can be reconstructed to be a high-resolut
