In order to improve operation efficiency and customer satisfaction and to minimize the turnaround time of vessels at container terminals, a berth allocation problem (BAP) was formulated. An adaptive artificial fish swarm algorithm (AFSA) was proposed to solve it. Firstly, the basic principle and the algorithm design of the AFSA were introduced. Then, for a test case, computational experiments explored...
According to the Characteristics of complex object system, a comprehensive evaluation model for complex object system is established based on fuzzy theory and artificial neural network. To realize the intelligence and the visualization of the evaluation process, an intelligent comprehensive evaluation software system with the help of Visual Basic, database technique and MATLAB toolbox is designed...
We propose a robust background subtraction method for multi-view images, which is essential for realizing free viewpoint video where an accurate 3D model is required. Most of the conventional methods determine background using only visual information from a single camera image, and the precise silhouette cannot be obtained. Our method employs an approach of integrating multi-view images taken by multiple...
In many applications it is necessary to be able to classify images in a database accurately and with acceptable speed. The main problem is to assign different images to right categories. The later problem becomes more challenging while dealing with large databases with many categories and subcategories. In this paper we propose a novel classification method based on an adopted hierarchical Dirichlet...
This paper describes a modeling of movement object. A auto driving of the car is studied to reduce traffic accidents and traffic jam in late years. The experiment tries there control with the radio controlled car which did movement same as a car. The control of the radio controlled car controls the steering voltage on speed uniformity this time. The control method usually uses model predictive control...
Error metric is the key problem for generating level of detail of terrain surface, which affects the deviation between the number of triangles and triangular mesh. After analyzing various present methods of calculating error metric, we present an improved algorithm based on roughness. This paper takes the roughness which expresses relief amplitude to be an factor, by which we calculate the error metric,...
