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. We develop and analyse a total variation based variational model for the solution of this problem. This new… CONTINUE READING
