deconvolution

[DIP] Deconvolution : Richardson-Lucy deconvolutoin algorithm

Blurring을 결정하는 PSF (blur kenel이라고도 불림)가 알려진 경우 사용되는 non-blind deblurring algorithm의 대표적 기법. The algorithm is based on a PSF (Point Spread Function), where PSF is described as the impulse response of the optical system. The blurred image is sharpened through a number of iterations, which needs to be hand-tuned. 단점이라면, iteration을 많이 수행할수록 noise성분이 강화된다는 점임. (RL deconv를 사용할 때, 측정된 이미지(PSF에 의해 blur된..
