Ground-based cloud detection plays an essential role in meteorological research, and object segmentation techniques have recently been introduced to solve this issue. As a kind of object segmentation technique, interactive graph cut has emerged as a very powerful tool due to its effective segmentation ability. However, it requires users to provide labels for certain pixels as “object” or “background,”...
To improve the identification rate of the information on aircraft's HUD interface, GL Studio is adopted to quickly build the virtual instrument interface of HUD, which is driven by flight simulation equations. The virtual instrument interface of HUD is imported into three-dimensional vision system for the ergonomics evaluation of character type, font type and color of the displayed information. The...
Background modeling from a stationary camera is a crucial component in video surveillance. Traditional methods usually adopt single feature type to solve the problem, while the performance is usually unsatisfactory when handling complex scenes. In this paper, we propose a multi-scale strategy, which combines both texture and color features, to achieve a robust and accurate solution. Our contributions...
A b-coloring of a graph G is a proper coloring of the nodes of G such that each color class contains a node that has a neighbor in all other color classes. A fully dynamic algorithm is an algorithm used to support modifications (insertion or deletion) of nodes and edges in a network. Thus, in this paper we propose a fully dynamic distributed algorithm to maintain a b-coloring of a graph when its topology...
