Abstract:
Satellite images are one of the most important tools used by meteorologist to determine the weather conditions. It is also used to know the behavior of atmosphere. Particular region of the satellite image will helpful for meteorologist to determine weather conditions and atmosphere. In order to enhance the particular region of the satellite image, the conversion of low resolution to high resolution is needed. Also, images captured by the satellite will be transmitted at low resolution to minimize the transmission power. To improve the quality of the satellite image at receiver side is a challenging task in the field of Communication Engineering. The quality of satellite image will be improve using Discrete Wavelet Transform (DWT) based decomposition and bi-cubic interpolation method. Bi-cubic interpolation method will helpful for enhancing the edges of the objects in the satellite image. MATLAB software will be used for the simulation purpose. Comparison of different parameters like Mean Square Error (MSE), Root Mean Square Error (RMSE), and Peak Signal to Noise Ratio (PSNR) is also done for superiority of proposed method.
