Fast And Accurate Autofocus Control Using Guassian Standard Deviation And Gradient-Based Binning, Peter Dimeo, Lu Sun, Xian Du

Mechanical and Industrial Engineering Faculty Publication Series

We propose a fast and accurate autofbcus algorithm using Gaussian standard deviation and gradient-based binning. Rather than iteratively searching for the optimal focus using an optimization process, the proposed algorithm directly calculates the mean of the Gaussian shaped focus measure (FM) curve to find the optimal focus location and uses the FM curve standard deviation to adapt the motion step size. The calculation only requires 3-4 defocused images to identify the center location of the FM curve. Furthermore, by assigning motion step sizes based on the FM curve standard deviation, the magnitude of the motion step is adaptively controlled according …

Measuring The Perceived Leasing Price Of Empty Container In Shipping System, Hao Hu, Bo Du, Mehrdad Amirghasemi

SMART Infrastructure Facility - Papers

The container shipping activity has increased significantly with the growth of world economy and global trade. However, due to the imbalance of global trade, there is always an imbalance between import and export containers, which results in that some ports have a surplus of empty containers while the others have a deficit. At a surplus port, storage cost and repositioning cost for shipping companies increase inevitably; while at a deficit port, shipping companies have to lease or purchase empty containers to meet customers’ demand. Empty container repositioning is one of the most effective ways to solve such imbalance problem, however …
