Enhancement Of Satellite Image Resolution With Moving Objects

Satellite images are being used in many applications like Meteorology, Agriculture, Geology, Forestry, Landscape, Biodiversity, Planning, Education, Regional, Seismology and oceanography. The Enhanced satellite images make diagnostic details more obvious. The Image Enhancement is the main technique for improving the resolution and visual appearance of the image. One of the major issues in Image Enhancement is Wavelet Transform. The Wavelet Transform is the method which decomposes an image into a set of basic functions called Wavelets. These basis functions are limited in duration and are inherently local. A Resolution Enhancement technique is based on the Interpolation of the high-frequency subbands obtained by Discrete Wavelet Transforms (DWT). Bicubic interpolation is used as a intermediate stage for estimating high frequency components and it is more sophisticated than the nearest neighbor and bilinear techniques. The proposed technique has the advantages of superior resolution, sharper image and smoother edges. The PSNR improvement of the proposed technique is up to 7.19dB.
