We propose a visual-based online signature verification system in which the signer's pen tip is tracked. The input module of the system consists of only low-cost cameras (webcams) and does not need special equipment such as an electronic tablet. Online signature data is obtained from the images captured by the webcams by tracking the pen tip. The pen tip tracking is implemented by the sequential Monte...
In this paper, we propose a new particle swarm optimization (PSO), which is based on successive optimization in its parameter space, in order to overcome the difficulty for applying PSO to complex and high dimensional nonlinear optimization problems. The proposed PSO consists of two types of optimization procedures; optimization in its decision variable space and optimization in its parameter space...
This paper proposes a new method, multi-point Tabu search, for solving combinatorial optimization problems on the basis of the concept of Proximate optimality principle (POP). While the similarity measure of POP is defined using the concept of metric space on combinatorial optimization problems, some numerical simulations using several types of combinatorial optimization benchmark problems investigate...
