Comparison of direct blind deconvolution methods for motion-blurred images.
Direct methods for restoration of images blurred by motion are analyzed and compared. The term direct means that the considered methods are performed in a one-step fashion without any iterative technique. The blurring point-spread function is assumed to be unknown, and therefore the image restoration process is called blind deconvolution. What is believed to be a new direct method, here called ...
متن کاملBlind image deconvolution of linear motion blur
We present an efficient method to deblur images for information recognition. The method is successfully applied directly on mobile devices as a preprocessing phase to images of barcodes. Our main contribution is the fast identifaction of blur length and blur angle in the frequency domain by an adapted radon transform. As a result, the barcode recognition rate of the deblurred images has been in...
متن کاملInitialization of iterative parametric algorithms for blind deconvolution of motion-blurred images.
Performances of iterative blind deconvolution methods for motion-blurred images are usually reduced depending on the accuracy of the required initial guess of the blur. We examine this dependency, and a two-stage restoration procedure is proposed: First we perform a direct technique with a single straight-forward process to produce a rough initial estimate of the blur, and then an iterative tec...
متن کاملBlind Estimation of Motion Blur Parameters for Image Deconvolution
This paper describes an approach to estimate the parameters of a motion blur (direction and length) directly form the observed image. The motion blur estimate can then be used in a standard nonblind deconvolution algorithm, thus yielding a blind motion deblurring scheme. The estimation criterion is based on recent results about the general spectral behavior of natural images. Experimental resul...
متن کاملBlind Deconvolution of Noisy Blurred Images via Dispersion Minimization
In linear image restoration, the point spread function of the degrading system is assumed known even though this information is usually not available in real applications. As a result, both blur identification and image restoration must be performed from the observed noisy blurred image. This paper presents a computationally simple linear adaptive finite impulse response filter for blind image ...
