Satellite images are necessary in geographical information, medical, geosciences studies and defense monitoring. But the resolution is the drawback of satellite images. Their resolution is modified due to the height of the satellites orbits and instrument used. Image resolution enhancement methods are used to resolve the drawback of satellite images. Resolution enhancement is the essential application...
Satellite images play a major role in the analysis of land cover, topographic analysis, geosciences etc. There has always existed a tradeoff between the image resolution and the image cost. In this paper, a modified discrete wavelet transform and interpolation based technique is proposed for enhancing the resolution of satellite images having low resolution in such a way that a highly resolved satellite...
A novel interpolation method for resolution enhancement is proposed in this paper. This method estimates wavelet coefficients in the high frequency subbands from a low resolution image using our proposed filters. An inverse wavelet transform is then performed for synthesis of a higher resolution image. Experimental results show that our proposed method outperforms other commonly used schemes objectively...
