A Robust Method for Blind Deconvolution of Barcode Signals and Nonuniform Illumination Estimation
نویسندگان
چکیده
This paper deals with a joint nonuniform illumination estimation and blind deconvolution for barcode signals. Such optimization problems are highly non convex. A robust method is needed in case of noisy and/or blurred signals and nonuniform illumination. Here, we present a novel method based on a genetic algorithm combining discrete and continuous optimization which is successfully applied to data with very strong noise and blur.

Joint nonuniform illumination estimation and deblurring for bar code signals.
We present a novel joint nonuniform illumination estimation and deblurring method for bar code signals based on a penalized nonlinear squares objective function. The objective function is based on the proper parameterization of a bar code signal and nonuniform illumination as well as a regularization on the illumination using a smoothness penalty. By the minimization of the objective function, ...

This research examines methods of implying deconvolution to blurry barcode signals with noise. Our goal is to to take these signals and recontrust them, using Yu Mao’s method of Gradient Projection, to be as clear as possible. This research examines the work of Yu Mao [5], alumni from the University of Minnesota. Our research is motivated by Yu Mao’s findings for how to reconstruct binary funct...
متن کاملPSO-Optimized Blind Image Deconvolution for Improved Detectability in Poor Visual Conditions
Abstract: Image restoration is a critical step in many vision applications. Due to the poor quality of Passive Millimeter Wave (PMMW) images, especially in marine and underwater environment, developing strong algorithms for the restoration of these images is of primary importance. In addition, little information about image degradation process, which is referred to as Point Spread Function (PSF...
متن کاملBlind Deconvolution of Bar Code Signals
Abstract Bar code reconstruction involves recovering a clean signal from an observed one that is corrupted by convolution with a kernel and additive noise. The precise form of the convolution kernel is also unknown, making reconstruction harder than in the case of standard deblurring. On the other hand, bar codes are functions that have a very special form – this makes reconstruction feasible. ...
متن کاملA Noise-Robust Method with Smoothed ℓ1/ℓ2 Regularization for Sparse Moving-Source Mapping
The method described here performs blind deconvolution of the beamforming output in the frequency domain. To provide accurate blind deconvolution, sparsity priors are introduced with a smoothed `1/`2 regularization term. As the mean of the noise in the power spectrum domain depends on its variance in the time domain, the proposed method includes a variance estimation step, which allows more rob...
