Management of multi-modal data is a classical problem in data mining and exploration. Geographic Information Systems usually store multi-modal data and employ them in spatial and image analysis. This paper proposes a fusion of multi-modal data in the context of line detection with Fuzzy Hough Transform (FHT). The goal of this work is to simulate the Roman streets according to periods from parti...

In order to realize 3D modeling and refinement of buildings in a digital 2D residential map using range images of the streets, we match range images of streets with the digital map. After pattern lines of the range images are determined using edge detection and depth analysis, they are matched with pattern lines of the digital map using a pattern matching algorithm based on dynamic programming....

The availability of very high spatial resolution satellite images over urban areas is recent. The very high spatial resolution enables a real representation of streets on a map, but generates a significant increase of noise. A state-of the-art on road and street extraction with the evolution from linear to surface models for road and street is proposed. Then, a method for extracting urban stree...

Two players are lost in a grid of city streets and wish to meet as soon as possible. Knowing only the distribution of the other’s initial location (two nodes away in one of the four compass directions), how do they move from intersection to intersection (between nodes of the lattice Z) to achieve this? We assume that they do not have common compass directions to coordinate on, but that they can...

R310 Current Biology 26, R307–R318, April 25, 2016 Most European cities have since the 1970s pedestrianised their main shopping streets and taken additional measures to keep cars out of the narrower streets of the historic centres. The Netherlands, now known as a paradise for cyclists, did not become one due to the genetic disposition of the inhabitants but due to conscious planning decisions d...

The scope of this paper is to outline, in a general way, the safety philosophy inherent in present roadand street design, trace the origin of this philosophy, and to present the principles for a new design of streets and roads. It will be argued that deficiencies in the present road design philosophy are the main cause of the global road safety crisis, clearly indicating its man-made nature. A ...

Traffic monitoring cameras are widely installed on streets and freeways in U.S. metropolitan areas. Video images captured from these video cameras can be used to extract many valuable traffic parameters through video image processing. A popular way to capture these traffic data is to compare the current traffic images with the background image, which contains no vehicles or other moving objects...

This paper presents an approximation of navigation problem under unknown environment using reinforcement learning. The motivation is to represent a robot that can move in a world with streets and intersections. Each intersection has a different quantity of streets (irregular blocks). The selected algorithms were Q-Learning and Value Iteration. The robot was programmed only with Q-Learning and w...

areas came to Calcutta in large numbers in search of food and work. Those that were unsuccessful in their quest made the open streets their home, and many of these in course of time reached the stage of advanced inanition. Arrangements had to be made to pick them up from the streets and send them to emergency hospitals for treatment and care. It was found that about 25 per cent of the cases rem...
