This paper addresses the nonstationary out-of-focus (OOF) blur removal in the application of barcode reconstruction. We propose a partially blind deblurring method when partial knowledge of the clean barcode is available. In particular, we consider an image formation model based on geometrical optics, which involves the point-spread function (PSF) for the OOF blur. With the known information, we can estimate a low-dimensional representation of the PSF using the Levenberg--Marquardt algorithm… 
Non-Blind Deconvolution of Blurred 1 D Barcodes Summer Research Program : iCAMP Barcode Deblurring Box Constraint
TLDR
This research develops an efficient non-blind deconvolution of a barcode using the box constraint and extensions of it, and experiments with slightly different methods to numerically estimate a bar code with gradient projection from an initial blurry image.

TLDR
The variational Bayesian SR technique in the barcode auto-identification technique should open a further perspective of coping with technology challenge and increase certainly the reconstruction quality, and could be considerably robust against blur and noise.

Convex blind image deconvolution with inverse filtering
Blind image deconvolution is the process of estimating both the original image and the blur kernel from the degraded image with only partial or no information about degradation and the imaging

TLDR
It is shown that a box relaxation is equivalent to the binary constraint for Fourier-types of phase retrieval, and it is proved that binary signals can be recovered uniquely up to trivial ambiguities under certain conditions.

A comparison between the original technique and the improved method shows that independent component learning on the unit hypersphere by a Riemannian-gradient algorithm outperforms the adapt-and-project strategy.
