To generate high resolution image from a low resolution input image single image super resolution is used. Single image super resolution is used to enhance the quality of image. In this paper there is a image super resolution algorithm is proposed which is based on GPS Gradient Profile Sharpness. Extract GPS from two gradient profile description models.GPS contain two model one is triangle model and second is mixed Gaussian model. Finally the HR(High Resolution)image is generated which has better visual Quality, lower resolution error. The aim of single image super resolution is to construct a high resolution image from LR(low resolution)image input. transformation gradient profiles to generate the target gradient field in HR image.
