Super-resolution technique is used for resolution enhancement. In Multiframe Super-resolution multiple low resolution images are combined to get high resolution image. Most important part of Multiframe Super-resolution is Image Registration that estimates translation,rotation and scaling parameters. In this paper they propose combination of PCA and GPOF registration method for constructing high resolution image. In GPOF registration method, which reach the sub pixel precision and allow large pixel motions and then apply PCA method which is used for compression of image. Image fusion is applied to get one output image. Then bicubic interpolation is used to get high resolved image. Experiment images show that the HR image by our proposed method has much higher quality than other methods.

Super-resolution technique is used for resolution enhancement. In multiframe super-resolution multiple low resolution images are combined to get high resolution image.This paper addresses multiframe super-resolution in which one or more low resolution images are combined to get high resolution image which can increase spatial resolution of image and different image quality matrices to measure the quality of the original image and reconstructed image.
