Once the blur class of the blurred regions is confirmed, the ... Restoration of defocused and blurred images by Vladimir Yuzhikov Restoration of distorted images is one of the most interesting and important problems of image processing - from the theoretical, as well as from the practical point of view.

Abstract- In image restoration, it is nearly always assumed that the point-spread function of the degrading system, as well as the variance of the observation noise and a model of the original image, is known a priori. Since these parameters are unknown for practical images of interest, they have to be estimated from the noisy blurred images In conclusion, the feasibility of optical limiting by digital restoration of intentionally blurred images has been demonstrated. High equivalent optical densities can be expected with this technique. The simplicity of this fast method, commonly used in image processing systems, should enable a real-time implementation at video rate. The knife-edge function can be used to model various types of motion-blurs, and hence it allows for the construction of a PSF and accurate estimation of the degradation function without knowledge of the specific degradation model. This paper addresses the problem of image restoration using a knife-edge function and optimal window Wiener filtering. English: Image restoration (motion blur, Wiener filter). Deblured in GNU Octave.

Sep 07, 2015 · As we know, the more an image is blurred, the less edges there are. Obviously the trick here is setting the correct threshold which can be quite domain dependent. Too low of a threshold and you’ll incorrectly mark images as blurry when they are not. Too high of a threshold then images that are actually blurry will not be marked as blurry.

Abstract- In image restoration, it is nearly always assumed that the point-spread function of the degrading system, as well as the variance of the observation noise and a model of the original image, is known a priori. Since these parameters are unknown for practical images of interest, they have to be estimated from the noisy blurred images
