Human activity understanding from three-dimensional data, such as from depth cameras, requires viewpoint-invariant matching. In this paper, we propose a new method of constructing invariants that allows distinction between isometries based on rotation, which preserve handedness, and those that involve reflection, which reverse right and left hands. The state-of-the-art in viewpoint invariants uses...
There are, of course, a multiplicity of factors that will affect the time taken to construct a particular project. Using grey relational analysis, we can find the core factors influencing construction duration. The objective of this paper is to provide a tool based on grey relational analysis to aid clients and their consultants in estimating or benchmarking the construction duration. For the construction...
In this study, a multi-criterion decision-making methodology using the Fuzzy Comprehensive Evaluation (FCE) and Attribute Hierarchy Model (AHM) was provided to assist decision-makers in selecting the proper contractors for their projects. Firstly, the evaluating bids were discussed and indices of evaluating bids were proposed. Then, the indices of evaluating bids such as ?? Quality standard, Construction...
With the need for improved performance in the construction industry and increasing contractual obligations, the requirement of an effective risk management approach has never been more necessary. In this paper, a new approach to construction project risk assessment based on rough set and information entropy is proposed. Firstly, the construction project risk evaluation index system is established,...
