We propose a method for improving image resolution. The method consists of an interpolation and a sharpening process. We research about some interpolations for producing high resolution images and show the properties of the interpolations in the frequency domain. Based on the research, we selected Lanczos function for the interpolation and applied the sharpening method which uses weighted sum of cubic operations of the pixel differences to the interpolated image. Experimental results also show that the sharpening with Lanczos interpolation gives clear high resolution images.

In order to improve image resolution, any interpolation has to be applied. However, in general, interpolation generates smooth connections between adjacent sampling points and yields blurred edges in the interpolated image. To suppress such a blur in edges, it is desired to include any sharpening effect in the interpolating process. In this paper, we propose a sharpening method using cubic operations of the differences of pixel values. Experimental results show that this method produces sharp high resolution image which is more similar to a target image than that by any other method.

“…Recently, super‐resolution with non‐linear signal processing (SRNL) was proposed . Although SRNL is a simple algorithm and it does not use a frame memory, it can create frequency elements higher than those of the original video.…”
