Abstract
Optimal linear prediction (OLP) as applied to form oversampled signals from undersampled signals is considered. The OLP-based algorithm for aliasing suppression and sampling frequency enhancement of an image that accumulates a series of geometrically distorted undersampled images is proposed. Results of numerical experiments showing the significant quality improvement for images constructed by OLP are given.
