Parallel Vectoring Algorithm for Pattern Matching

Parallel Vectoring Algorithm for Pattern Matching

The main aim of this study is to propose efficient algorithms for image template matching on parallel machines. To our knowledge there is no a template matching algorithm that converts the template image and all candidate blocks in the source image from two-dimensions into one-dimension. This study proposes a Template Matching Vectoring Algorithm (TMVA) that reduces the amount of data to be ana...

Parallel Pattern Matching with Scaling

Bit-Parallel Multiple Pattern Matching

Text matching with errors is a regular task in computational biology. We present an extension of the bit-parallel Wu-Manber algorithm [16] to combine several searches for a pattern into a collection of fixed-length words. We further present an OpenCL parallelization of a redundant index on massively parallel multicore processors, within a framework of searching for similarities with seed-based ...

A Quantum Algorithm for Closest Pattern Matching

We propose a quantum algorithm for closest pattern matching which allows us to search for as many distinct patterns as we wish in a given string (database), requiring a query function per symbol of the pattern alphabet. This represents a significant practical advantage when compared to Grover’s search algorithm as well as to other quantum pattern matching methods [7], which rely on building spe...

Genetic algorithm for affine point pattern matching

Point pattern matching (PPM) is an important topic in the fields of computer vision and pattern recognition. According to if there exists a one to one mapping between the two point sets to be matched, PPM can be divided into the case of complete matching and the case of incomplete matching. According to if utilizing information other than 2-D image coordinates, PPM can be divided into labelled ...
