One of the most significant achievements in digital photogrammetry in the last decade is the development of large format digital mapping cameras. In addition to large format digital mapping cameras, a number of medium format digital mapping cameras systems have also been developed. At Pictometry, a medium format digital imaging system has been developed and been widely used for acquisition of b...

Orientation perception is not comparable across all orientations-a phenomenon commonly referred to as the oblique effect. Here, we first assessed the interaction between stimulus contrast and the oblique effect. Specifically, we examined whether the impairment in behavioral performance for oblique versus cardinal orientations is best explained by a contrast or a response gain modulation of the ...

[1] Past plate motion between East and West Antarctica along the West Antarctic rift system had important regional and global implications. Although extensively studied, the kinematics of the rift during Eocene-Oligocene time still remains elusive. Based on a recent detailed aeromagnetic survey from the Adare and Northern Basins, located in the northwestern Ross Sea, we present the first well-c...

This paper focuses on the processing and study of 3D models obtained from images captured by an unmanned aerial vehicle (UAV). In particular, we wanted to study the accuracy gains achieved in the surveying and the measurement, such as height, area, and volume, of the dimensions of the buildings in the 3D models obtained with both nadir and oblique UAV flights. These latter types of flights are ...

This study has been inspired by the paper "An efficient 3D topology optimization code written in MATLAB” written by Liu and Tovar (2014) demonstrating that SIMP-based three-dimensional (3D) topology optimization of continuum structures can be implemented in 169 lines of MATLAB code. Based on the above paper, we show here that, by simple and easy-to-understand modificati...

We describe the initial efforts towards developing a system for automatically generating oblique 3D overviews of hiking trails. Given a GPS path, the system is intended to automatically return a printable map with an appropriately chosen viewpoint and vertical distortion. We discuss general design implications for 3D maps and map-related representations, address specific applications to this ta...

A stereo mosaic representation has been developed for fusing imaging data captured by sensors (cameras) in motion. In addition to providing a wide field of view, the multiperspective mosaics with various oblique views represent occlusion regions that cannot be achieved by using stationary sensors. One or multiple stereo pairs can be formed from mosaics with different oblique viewing angles and ...

[Purpose] The present study examined the activity and the gait characteristics of the gluteus medius and the trunk stability muscles during the stance phase of gait on level ground when a vertical load corresponding to 0%, 1%, or 2% of body weight was placed on the lower extremities during the swing phase of the gait. [Methods] The subjects were 40 young males aged between 21 and 30 years. The ...

ABSTRACT: With the development of 3D city model and 3D Geographic Information Systems (GIS), the models of buildings provide many applications like urban planning, disaster assessment, virtual visualization, and others. For city models production, aerial images and photogrammetry are definitely important data source and technology for building reconstruction, since rich geometric and semantic i...
