Abstract :

in this correspondence we propose a technique for augmentation of image resolution based on wavelets which has a certain capability to analyze non-stationary signals. Satellite images are being used in many fields of research. One of the major issues of these types of images is their resolution. The discrete wavelet transform and unprocessed image is used to obtain interpolation of the high frequency sub-band images. In intermediate stage stationary wavelet transform is used to enhance the edges of image. The decomposition of input image to obtain frequency sub-bands is done by discrete wavelet transform. Then the high frequency sub-bands as well as the input image are interpolated. The high frequency sub-bands obtained by SWT are being used to modify estimated high frequency sub-bands. Then inverse discrete wavelet transform is used to combine all these sub-bands from which a new high resolution image is generated. The quantitative peak signal-to-noise ratio and enhanced visual features of the subject images shows the superiority of the proposed technique over the conventional bicubic interpolation, wavelet zero padding and bilinear interpolation based image resolution enhancement techniques.
