Large-Scale Vector Data Displaying for Interactive Manipulation in 3D Landscape Map
3D Landscape Map Large-scale Vector Data Manipulation Displaying
2015/12/16
Displaying large-scale 3D vector data in landscape map is very important, as 3D vector data can provide many important information, such as: precise geographic boundaries, areas, 3D text marks, differ...
AUTOMATIC IMAGE SEQUENCE REGISTRATION BASED ON A LINEAR SOLUTION AND SCALE INVARIANT KEYPOINT MATCHING
Aerial Triangulation Linear solutions Scale invariant feature transform Essential matrix image correspondence
2015/8/14
Automatic registration of image sequences has been a subject of research for many years, both in the photogrammetric and computer
vision communities. As part of the automation, linear orientation me...
An interior point method for large-scale l1-regularized least squares
Sparse signal the compressed sensing signal processing statistics least squares procedure
2015/8/10
Recently, a lot of attention has been paid to l1 regularization based methods for sparse signal reconstruction (e.g., basis pursuit denoising and compressed sensing) and feature selection (e.g., the L...
An interior-point method for large-scale network utility maximization
Newton the interior point networks concave utility functions disperse method dual decomposition algorithm
2015/8/10
We describe a specialized truncated Newton primal-dual interior-point method that solves large scale network utility maximization problems, with concave utility functions, efficiently and reliably. Ou...
The Novice-Expert ratio Method (NEM) compares the time it takes a novice user to complete each step of a task with the time it takes an expert user to complete the same step. A high ratio indicates th...

Large-Scale Cross-Media Retrieval WikipediaMM Images
2010/12/20
In this paper, we present our approaches for the WikipediaMM task at ImageCLEF 2008. We first experimented with a text-based image retrieval approach with query expansion, where the extension terms we...
Image Objects and Multi-Scale Features for Annotation Detection
Image Objects Multi-Scale Annotation Detection
2010/12/17
This paper investigates several issues in the problem of detecting handwritten markings, or annotations, on printed documents. One issue is to define the appropriate units over which to perform featur...
When an image is viewed at varying resolutions,it is known to create discrete perceptual jumps or transitions amid the continuous intensity changes. In this paper,we study a perceptual scale-space the...
