This study has developed a framework for adoption of geospatial governance in the context of e-government in Tanzania. After examining the governance of geospatial data, identify factors affecting gov...
ROAD NETWORK EXTRACTION FROM SAR IMAGERY SUPPORTED BY CONTEXT INFORMATION
Mapping SAR Object Extraction
2015/6/1
This paper deals with automatic road extraction from SAR imagery. In general, automatically extracted road networks are not complete,
i.e., gaps remain in the erxtracted network. Especially in SAR im...
Context-adaptive Pixel Based Prediction for Intra Frame Encoding
Context-adaptive Pixel Based Prediction Intra Frame Encoding
2010/12/21
Intra prediction is one effective method to remove the spatial redundancies in intra frame coding. Better intra prediction will result in the residual with less energy, which
will decrease the number...

AN ALGORITHM FOR THRESHOLDING IN THE CONTEXT OF SIGNAL DENOISING WITH WAVELETS
signal processing analysis denoising filtering
2010/1/11
The problem of estimating a signal corrupted by additive noise has been of
interest to many researchers for practical as well as theoretical reasons. Wavelet based
methods have become increasingly p...
An Enhanced Robust Entropy Coder for Video Codecs Based on Context-Adaptive Reversible VLC
Enhanced Robust Entropy Coder Video Codecs Context-Adaptive Reversible VLC
2010/12/17
Reversible variable length coding (RVLC) is an important robust entropy coding
technique for error resilient video transmission. The popular DCT-based video codecs all
can use it. RVLC supports both...
Context-based Arithmetic Coding Reexamined for DCT Video Compression
Context-based Arithmetic Coding DCT Video Compression
2010/12/17
This paper presents a new context modeling technique for arithmetic coding of DCT coefficients in video compression. A key feature of the new technique is the inclusion of all previously coded coeffic...
A context-based adaptive fast Intra_4x4 prediction mode decision algorithm for H.264/AVC video coding
context-based fast Intra_4x4 prediction mode decision algorithm H.264/AVC video coding
2010/12/17
In this paper, we propose a context-based adaptive fast Intra_4x4 prediction mode decision algorithm for H.264/AVC. Firstly, a 3-order Markov random field model is introduced to describe the spatial d...
High Efficient Context-Based Variable Length Coding with Parallel Orientation
Context-Based Variable Length Coding Parallel Orientation
2010/12/15
Entropy coding is one of the most important techniques in video codec.Two main criteria to assess an entropy coder are coding efficiency and friendly realization characteristic. In the recent developm...
It is well observed that usually the run-length of successive zero coefficients becomes longer and the magnitude of non-zero coefficients gets smaller while the DCT subband frequency increases. So the...
