The problem visual place recognition is commonly used strategy for localization. Most successful appearance based methods typically rely on a large database of views endowed with local or global image descriptors and strive to retrieve the views of the same location. The quality of the results is often affected by the density of the reference views and the robustness of the image representation...

Vehicle-based image sequence is taken on a moving vehicle, therefore, all scenes passed by will be included, e.g. buildings, crossroad etc.. Images including cross-road are obviously useless for building facade texture. Therefore, those images should be excluded from processing. In this paper, subsection of image sequence is implemented according to range variance automatically detected by the ...

Building facade detection is an important problem in computer vision, with applications in mobile robotics and semantic scene understanding. In particular, mobile platform localization and guidance in urban environments can be enabled with accurate models of the various building facades in a scene. Toward that end, we present a system for detection, segmentation, and parameter estimation of bui...

A test of nonfinancial measures used as part of a management-incentive program by a U.S.-based, full-service hotel chain found that improvements in the nonfinancial measures were followed shortly by increases in revenue and profit. The two nonfinancial measures are customer satisfaction as measured by guests’ comment card indications of likelihood to return and level of complaints. The lag betw...

Three-dimensional (3-D) modeling of urban environments has numerous applications, including virtual environments, urban planning, and physical simulation. Constructing 3-D models from photographs (images) is thus an important area of research in computer vision, and increasingly, computer graphics. However, despite many years of research, a system that automatically recovers realistic 3-D model...

Extraction of a digital elevation model from high resolution satellite images such as IKONOS is important for many applications. One of the most popular techniques hired for automated DEM extraction is stereo matching. However, high resolution satellite images possess some properties that make automated stereo matching difficult. They present edges of individual buildings, building facades and ...

Data from the Hyperspectral Mapper (HyMap), which is acquired with a field of view (FOV) of 61.3 degrees, is disturbed by the bidirectional behavior of the covered surface and its complex geometry. The resulting phenomena, an across-track brightness gradient and spectral differences caused by shifted objects, were described and analyzed in detail. An appropriate correction method for the object...
