This paper introduces a new algorithm for improving the resolution of interpolated video. The aim is to achieve a high resolution video from a low resolution one. The new algorithm uses the concept of interpolation and filtering in order to get a higher resolution video. The filter is designed by reducing the size of the video and then enlarging it by using interpolation. A filter is optimized to...
This paper presents a new algorithm for improving the resolution of satellite images. The improvement aims at obtaining a high resolution image from a single low resolution image. The new algorithm utilizes interpolation and two dimensional filter specifically designed for a particular image by means of maximizing the peak signal to noise ratio (PSNR). The performance of the algorithm is evaluated...
This paper deals with the design and analysis of 2D filters for improving the resolution of interpolated satellite images. The images are reduced first by a certain factor and then interpolated back to the original size. Linear phase 2D filters are designed to optimize the structural similarity index measure (SSIM). Then the satellite image is enlarged by the same factor and the 2D filter is used...
The resolution of satellite images is controlled by the number of imaging sensors on board the satellite. Once the satellite is launched then this resolution cannot be changed during the lifetime of the satellite. The only way to increase the resolution of the images is by using super-resolution techniques. This paper deals with the design and analysis of 2D filters for improving the resolution of...
