A novel technique via Quadtree Gauss-Laguerre Transform (LGT) for a complete localization of a complex image in an multimedia database is presented. This technique is based on an iterative Maximum Likelihood procedure that allows to compare a region of interest (ROI) of an image with a content of a database, independently from location, rotation and scale. At this aim the ROI is expanded in terms...
This paper proposes a local augmentation and integrity monitoring network for railway and shows the obtained performances in terms of accuracy positioning in case of satellite faults. The simulations results show that the system can detect and discard tha faulty satellite, still mantaining the accuracy on positioning accetable. The work is inserted in the scenario of introduction and application of...
