摘要: In image deconvolution, the boundary value problem, if not appropriately handled, often causes serious ringing artifacts in restored results. This paper proposes a simple method to tackle this problem without any assumption on noise level and symmetry of Point Spread Function (PSF). We establish new conditions by smoothly expanding input large tile. It helps reducing discontinuities accordingly makes all restoration filters based Fast Fourier Transform (FFT) produce obvious border artifacts.
