Abstract: Photographs which are blurred, for example, by uniform motion of a camera relative to an image during exposure, are restored by identifying certain parameters of the blurring, e.g., direction and displacement, using the parameters to transform the distortion into an additive periodic component in the picture (blur), and by estimating (or identifying) and subtracting the periodic components from the picture. Two-dimensional spectral analysis, or the cepstrum technique, may be employed to identify the blur parameters, and a transversal filter arrangement, adjusted in accordance with parameter values is used to perform the estimation and subtraction.
