This article presents a novel vehicle edge detection algorithm based on Canny operator in nighttime environment. Firstly, spatial homomorphism filtering is used to eliminate the illuminating influence; then an improved self-adaptive fuzzy enhancement Canny operator is used to enhance the vehicle edge; lastly the maximum classification square error method is used to calculate the dual threshold, performing...
Construction site layout is multi-objective optimization (MOO) problem. However, the previous researchers treated site layout as a single objective optimization problem, which is far away from the reality. In this study, site layout was treated as MOO problem. The two objective functions are minimizing the likelihood of accidents happened and total handling cost of interaction flows between the facilities...
The algorithm of locally adaptive clustering for high dimensional data (LAC) processes soft subspace clustering by local weightings of features. To solve the localization of LAC in specifying the number of clusters, this paper reworks the validity index for fuzzy clustering to evaluate the clustering results of LAC. Compared with real clustered data, the method is proved feasible. In the new algorithm,...
