A symbol-based algorithm for decoding bar codes
Mark Iwen, Fadil Santosa, Rachel Ward
We investigate the problem of decoding a bar code from a signal measured with a hand-held laser-based scanner. Rather than formulating the inverse problem as one of binary image re…
Near-optimal compressed sensing guarantees for total variation minimization
Deanna Needell, Rachel Ward
Consider the problem of reconstructing a multidimensional signal from an underdetermined set of measurements, as in the setting of compressed sensing. Without any additional assump…
Two-subspace Projection Method for Coherent Overdetermined Systems (Technical Report)
Deanna Needell, Rachel Ward
In this technical report we present a Projection onto Convex Sets (POCS) type algorithm for solving systems of linear equations. POCS methods have found many applications ranging f…
