The Processing of Image Data Collected by Light UAV Systems for GIS Data Capture and Updating
UAVs, Photogrammetry Sensor Orientation DEM, orthoimage GIS
2014/4/22
The collection and updating of 3D data is the one of the important steps for GIS applications which require fast and efficient data collection methods. The photogrammetry has been used for many years ...
FULLY AUTOMATIC IMAGE-BASED REGISTRATION OF UNORGANIZED TLS DATA
Laser Scanning TLS point cloud registration image-based graph-based automation
2014/6/5
The estimation of the transformation parameters between different point clouds is still a crucial task as it is usually followed by scene reconstruction, object detection or object recognition. Theref...
IMAGE-BASED DEFORMATION MONITORING OF STATICALLY AND DYNAMICALLY LOADED BEAMS
close range digital photogrammetry camera image acquisition three-dimensional precision reconstruction
2014/4/25
Structural health monitoring of civil infrastructure systems is an important procedure in terms of both safety and serviceability. Traditionally, large structures have been monitored using surveying t...

2010/12/20
The new trend of online advertisement is in-image advertising, which is facing the risk of being intrusive.Several works have been done to reduce the intrusiveness. However, intrusiveness is a subject...
Image Quality Assessment Using Spatial Frequency Component
Image Quality Assessment Spatial Frequency Component
2010/12/20
Image quality assessment (IQA) is a crucial technique in perceptual image/video coding, because it is not only a ruler for performance evaluation of coding algorithms but also a metric for ratio-disto...
A Fast Approach for Natural Image Matting Using Structure Information
Natural Image Matting Structure Information
2010/12/17
Natural image matting plays an important role in image and video editing. It has been addressed hotly because it is inherently an under-constrained problem – we must estimate
both the foreground and ...
