Satellite Image Enhancement using DWT – SWT Method

Abstract

In the area of image processing, Satellite imaging is one of the challenging assignments for the analysts. The diverse satellite sensors are accessible in the low range to high range for information gathering. In our paper, a satellite image enhancement algorithm based on interpolation of the high-frequency subbands acquired by discrete wavelet transform (DWT) and the low resolution input image is proposed. This technique utilizes a DWT and high frequency subband image interpolation into the low resolution input images. The sharpness of image is acquired by the estimation of high frequency subband. we have combined DWT with SWT and improve the quality of the image.  Inverse DWT is performed to recreate the resultant image. The visual and mathematical outcomes are exhibited and talked about on LANDSAT 8 information by comparing the proposed method over conventiossnal and condition of resolution enhancement methods.
