A low cost structured light system
(2005-12-01)
The aim of this paper is to present the current development status of a low cost system for surface reconstruction with structured light. The acquisition system is composed of a single off-the-shelf digital camera and a ...
Image registration and image interpolation in volume rendering of cross sections
(1995-12-01)
We outline a method for registration of images of cross sections using the concepts of The Generalized Hough Transform (GHT). The approach may be useful in situations where automation should be a concern. To overcome known ...
Georeferenced road extraction and formulation of hypotheses for new road segments
(2000-01-01)
The acquisition and update of Geographic Information System (GIS) data are typically carried out using aerial or satellite imagery. Since new roads are usually linked to georeferenced pre-existing road network, the extraction ...
USING RELATIVE ORIENTATION CONSTRAINTS TO PRODUCE VIRTUAL IMAGES FROM OBLIQUE FRAMES
(Copernicus Gesellschaft Mbh, 2012-01-01)
Image acquisition systems based on multi-head arrangement of digital cameras are attractive alternatives enabling larger imaging area when compared to a single frame camera. The calibration of this kind of systems can be ...
Using relative orientation constraints to produce virtual images from oblique frames
(2012-01-01)
Image acquisition systems based on multi-head arrangement of digital cameras are attractive alternatives enabling larger imaging area when compared to a single frame camera. The calibration of this kind of systems can be ...
Conceptual model for adaptable and extensible visual data exploration
(2004-12-01)
Interactive visual representations complement traditional statistical and machine learning techniques for data analysis, allowing users to play a more active role in a knowledge discovery process and making the whole process ...
REGISTRATION AND FUSION OF MULTIPLE IMAGES ACQUIRED WITH MEDIUM FORMAT CAMERAS
(Copernicus Gesellschaft Mbh, 2010-01-01)
Recent developments in the technology of optical digital sensors made available digital cameras with medium format at favourable cost/benefit ratio. Many companies are using professional medium format cameras for mapping ...
Registration and fusion of multiple images acquired with medium format cameras
(2010-01-01)
Recent developments in the technology of optical digital sensors made available digital cameras with medium format at favourable cost/benefit ratio. Many companies are using professional medium format cameras for mapping ...
Efficient sign language recognition system and dataset creation method based on deep learning and image processing
(2021-01-01)
New deep-learning architectures are created every year, achieving state-of-the-art results in image recognition and leading to the belief that, in a few years, complex tasks such as sign language translation will be ...
Velocity estimation of a mobile mapping vehicle using filtered monocular optical flow
(2007-01-01)
Generally, a road image sequence acquired by a mobile mapping system (MMS) is oriented by integrating the Global Positioning System (GPS) and an inertial navigation system (INS) data. Alternatively, this article presents ...
