Abstract. The use of drones to explore indoor spaces has gained attention and popularity for disaster management navigation applications. In this paper we present the operations mapping techniques two that are different in terms size, sensors deployed, positioning used. first drone is a low-cost commercial quadcopter microdrone, Crazyflie, while second relatively expensive research macrodrone, ...

The development and performance of a system for x-ray cone-beam computed tomography (CBCT) using an indirect-detection flat-panel imager (FPI) is presented. Developed as a bench-top prototype for initial investigation of FPI-based CBCT for bone and soft-tissue localization in radiotherapy, the system provides fully three-dimensional volumetric image data from projections acquired during a singl...

With increasing research in the area of face segmentation, new methods for detecting human faces automatically are being developed. However, less attention is being paid to the development of a standard face image database to evaluate these new algorithms. This paper recognizes the need for a colour face image database and creates such a database for direct benchmarking of automatic face detect...
