Optical Implementation of a Single-Iteration Thresholding
نویسندگان
چکیده
Threshold (or relative magnitude) search is traditionally performed iteratively in a bit-serial manner in optical database/knowledge-base machines which results in an execution time proportional to the operand size. We present in this paper a single-step threshold search algorithm and its optical implementation. The proposed algorithm performs magnitude comparison in constant time, independent of the operand size, and consequently, it greatly increases the performance of optical database/knowledge-base processing operations such as searching, selection, retrieving, and sorting.

متن کاملA Fast Implementation of Singular Value Thresholding Algorithm using Recycling Rank Revealing Randomized Singular Value Decomposition
In this paper, we present a fast implementation of the Singular Value Thresholding (SVT) algorithm for matrix completion. A rank-revealing randomized singular value decomposition (RSVD) algorithm is used to adaptively carry out partial singular value decomposition (SVD) to fast approximate the SVT operator given a desired, fixed precision. We extend the RSVD algorithm to a recycling rank reveal...

متن کاملComparison of threshold-based algorithms for sparse signal recovery
Intensively growing approach in signal processing and acquisition, the Compressive Sensing approach, allows sparse signals to be recovered from small number of randomly acquired signal coefficients. This paper analyses some of the commonly used threshold-based algorithms for sparse signal reconstruction. Signals satisfy the conditions required by the Compressive Sensing theory. The Orthogonal M...
