Optimization and performance analysis of thinning algorithms on parallel computers
This paper presents a concept for an implementation of different parallel thinning algorithms on parallel processors. The emphasis is put on a good parallelization using fine granularity and the simultaneous usage of vectorization. Results and ...
Parallel Single and Multiple Objectives Genetic Algorithms: A Survey
This paper critically reviews the reported research on parallel single and multi-objective genetic algorithms. Many early efforts on single and multi-objective genetic algorithms were introduced to reduce the processing time needed to reach an ...
Some results concerning connected fuzzy digital pictures
A fuzzy digital picture is called 'connected' if it has only one connected component of constant fuzzy level that is maximal. In this paper, we prove three theorems concerning the connectedness of fuzzy digital pictures. The first theorem proves that ...
