High Accurate Estimation of Point Spread Function Based on Improved Reconstruction of Slant Edge

doi:10.11947/j.AGCS.2015.20140400

Abstract

Abstract: A high accurate estimation algorithm for point spread function which is free from edge slant angle is proposed. In this algorithm, high accuracy estimation of point spread function is gained by improved edge line fitting, sample denosing and anti-aliasing resampling. Compared with the existing slanted edge methods, the new method yields a significant improvement in accuracy and stability.

Key words: remote sensing image processing, degradation, point spread function, edge method
