A comprehensive study on face recognition: methods and challenges

ABSTRACT

Face Recognition is the process of identifying and verifying the faces. Face recognition has vast importance in the field of Security, Healthcare, Banking, Criminal Identification, Payment, and Advertising. In this paper, we have reviewed various techniques and challenges for the face recognition. Illumination, pose variation, facial expressions, occlusions, aging, etc. are the key challenges to the success of face recognition. Pre-processing, Face Detection, Feature Extraction, Optimal Feature Selection, and Classification are primary steps in any face recognition system. This paper provides a detailed review of each. Feature extraction techniques can be classified as appearance-based methods or geometry-based methods, such method may be local or global. Feature extraction is the most crucial stage for the success of the face recognition system. However, deep learning methods have freed the user from handcrafting the features. In this article, we have surveyed state-of-the-art methods of last few decades and the comparative study of various feature extraction methods is provided. Article also describes the current challenges in the area.     

Project Manager’s Decision Aid for a Radical Project Cycle Reduction

Currently there are no formal decision tools or guidelines to assist owners and project managers in choosing delivery systems and project strategies that would allow significant reductions in the project cycle time. The development of a decision aid that would allow a project manager to prioritize and apply project cycle reduction techniques would be a valuable tool for achieving project cycle time reduction in projects. This paper presents a new high performance project delivery system called “project manager’s game planner” (PMGP) designed to assist a decision maker in identifying and utilizing an optimal set of radical reduction techniques (RRTs) with the greatest potential for success in achieving cycle time reduction. Additionally, the PMGP can assist the user in identifying the top RRTs during any of the five project phases: preproject planning, design, material management, construction, and start-up. Most projects can utilize this PMGP to improve the project performance whether to achieve significant cycle time reduction or to simply achieve effective project execution.     

Analysis of Techniques Leading to Radical Reduction in Project Cycle Time

Today’s construction business relies on first-to-market product strategies to gain competitive advantages and increase profit margins. This has created an increased demand for a high performance capital project delivery system that can achieve a dramatic reduction in project cycle time. Very few decision tools and guidelines exist to assist owners in choosing appropriate delivery systems and project strategies to radically reduce the project cycle time from the preplanning stage through start up. The research presented in this paper surveyed the construction owners and architectural/engineering/construction firms to identify projects that have achieved greater than 25% reduction in overall project cycle time when compared to current industry standards. The data collected were analyzed to determine the techniques that facilitate radical reduction in project cycle time. These techniques include, best practices and schedule reduction techniques as well as the various management techniques employed on the projects identified by the Construction Industry Institute (CII). This research also identified the barriers to radical schedule reduction. The research concludes that radical schedule reduction well in excess of 25% can be achieved through the selective employment of management techniques, schedule reduction techniques and CII best practices. Almost every construction manager can utilize this research to improve project performance whether for radical reduction or simply more effective execution.
