AUTOMATED BUILDING DETECTION IN DENSE POINT CLOUD AND UPDATE OF OPEN SOURCE DATA BASES
Dense matching, Building detection Classification Digital Terrain Model openstreetmap point cloud
2018/11/9
In this paper a method of detecting buildings in dense populated city areas using a three-dimensional model, produced by aerial images, is described. Further to the detection of the outline of the bui...

2018/11/8
The GEO-ICT is an institutional cooperation project aiming at improving the quality and societal relevance of geospatial and ICT research and education at the Universities of Dar es Salaam (UDSM), Ard...
GENERATING ACCURATE 3D MODELS OF ARCHITECTURAL HERITAGE STRUCTURES USING LOW-COST CAMERA AND OPEN SOURCE ALGORITHMS
Structure-From-Motion Dense Point Cloud Mesh Open Source Algorithms Architectural Heritage
2017/6/20
These studies have been conductedusing non-metric digital camera and dense image matching algorithms, as non-contact methods of creating monuments documentation.In order toprocess the imagery, few ope...
A 3-node lossy source coding problem for a 2-DMS(X1, X2) is considered. Source nodes 1 and 2 observe X1 and X2, respectively, and each wishes to reconstruct the other source with a prescribed distorti...
Noisy network coding unifies network coding by Ahlswede, Cai, Li, and Yeung for noiseless networks and compress–forward by Cover and El Gamal for noisy relay channels.
We investigate distributed source coding of two correlated sources X and Y where messages are passed to a decoder in a cascade fashion. The encoder of X sends a message at rate R1 to the encoder of Y....
Denoising source separation
blind source separation BSS prior information denoising denoising source separation DSS independent component analysis ICA magnetoencephalograms MEG CDMA
2015/7/30
A new algorithmic framework called denoising source separation (DSS) is introduced. The main benefit of this framework is that it allows for easy development of new source separation algorithms which ...
EVALUATION OF SAR DATA AS SOURCE OF GROUND CONTROL INFORMATION: FIRST RESULTS
Georeferencing matching DEM/DTM SAR optical multisensor accuracy performance experiment
2014/4/24
The high resolution imaging modes of modern SAR sensors has made SAR data compatible with optical images. SAR data offers various capabilities which can enhance the geometric correction process of opt...
On Optimal Bit Allocation for Classification-Based Source-Dependent Transform Coding
Optimal Bit Allocation Source-Dependent Transform Coding
2009/9/4
An optimal bit allocation is presented for classification-based source-dependent transform coding. A vector of transform coefficients is considered to have been produced by a mixture of processes. The...
Discrete Array Representation of Continuous Space-time Source Distributions
slant stack transform ultra-wide band short-pulse signals continuous space-time source distribution
2009/7/28
We consider the realization of a continuous space-time source distributions using a sparse non-uniform point-source array. The construction determines the largest possible cells corresponding to the l...
Joint Source-Channel Rate-Distortion Optimization for H.264 Video Coding Over Error-Prone Networks
Joint Source-Channel Rate-Distortion H.264 Video Coding
2010/12/16
For a typical video distribution system, the video contents are first compressed and then stored in the local storage or transmitted to the end users through networks. While the
compressed videos are...
FBSA: A self-adjustable multi-source data scheduling algorithm for P2P media streaming
peer-to-peer media streaming data scheduling
2010/12/17
Recently, there is great interest of using P2P network in multi-source media streaming. In this paper, we present a self-adjustable scheduling algorithm for multi-source P2P media streaming, called fe...
