Error Estimates for a Bar Code Reconstruction Method

We analyze a variational method for reconstructing a bar code signal from a blurry and noisy measurement. The bar code is modeled as a binary function with a finite number of transitions and a parameter controlling minimal feature size. The measured signal is the convolution of this binary function with a Gaussian kernel. In this work, we assume that the blur kernel is known and establish condi...

Bar Code Waveform Recognition Using Peak Locations

adi it ion ally, zero crossings of the second derivative provide edge features for the classification of blurred waveforms. The accuracy of these edge features deteriorates in the case of severely blurred images. In this paper, a new feature is presented that is more resistant to the blurring process, the image, and waveform peaks. In addition, an estimate of the standard deviation of the blurr...

A Non-MDS Erasure Code Scheme for Storage Applications

This paper investigates the use of redundancy and self repairing against node failures indistributed storage systems using a novel non-MDS erasure code. In replication method, accessto one replication node is adequate to reconstruct a lost node, while in MDS erasure codedsystems which are optimal in terms of redundancy-reliability tradeoff, a single node failure isrepaired after recovering the ...

Real-time Optical Position Monitoring Using a Reference Bar

This paper presents a position monitoring system designed for a hand-held mine detector and based on a camera and an accelerometer. Real-time positioning during scanning allows the image reconstruction of the captured signals. Image representation enables object shape analysis and simplifies target localization. The system reports positions relatively to the bar with reference points placed on ...
