Theoretical Issues of Searching Aerial Photographs: A Bird's Eye View
نویسنده
چکیده
We review some pattern matching algorithms and techniques motivated by the discrete theory of image processing. The problem inspiring this research is that of searching an aerial photograph for all appearances of some object. The issues we discuss are digitization, local errors, rotation and scaling. We review deterministic serial techniques that are used for multidimensional pattern matching and discuss their strengths and weaknesses.

"Anywhere Augmentation": Towards Mobile Augmented Reality in Unprepared Environments
We introduce the term " Anywhere Augmentation " to refer to the idea of linking location-specific computing services with the physical world, making them readily and directly available in any situation and location. This chapter presents a novel approach to " Anywhere Augmentation " based on efficient human input for wearable computing and augmented reality (AR). Current mobile and wearable com...
متن کاملHead-Driven Phrase Structure Grammar Linguistic Approach, Formal Foundations, and Computational Realization
The theoretical richness, formal rigor and computational versatility of Head-driven Phrase Structure Grammar (HPSG) preclude any kind of in-depth coverage of its content within the confines of an encyclopedia article such as this. Our objectives are accordingly far more modest: we seek to provide a kind of aerial view of the linguistic approach (§2), summarize the formal foundations (§3), and c...

The United States Department of Transportation (DOT) has been interested for the past several years in obtaining data on traffic trends and to monitor and control traffic in realtime. Currently, there are several methods by which the DOT regulates and monitors road transport. Cameras mounted on towers, detectors embedded in pavements or pneumatic tubes, and unmanned aircraft have been proven to...
متن کاملSurface Transportation Surveillance from Unmanned Aerial Vehicles
Unmanned Aerial Vehicles (UAVs) promise a low cost means to achieve a "bird's eye view" and a rapid response for a wide array of transportation operations and planning applications, including incident response, coordination among a network of traffic signals, traveler information, emergency vehicle guidance, and measurement of typical roadway usage. However, many obstacles to operational use ex...

In this section we provide the form of the projection functions Pv(`, c) that convert from geographic locations to pixel locations in aerial view and street view images. We give the form of the inverse function P−1 v (`′, c) that converts from pixel locations to geographic coordinates. Aerial images: Aerial view imagery in Google maps is represented using a Web Mercator projection, a type of cy...
