Disaster Management Large Spatial Database Shortest Path Dijkstra Algorithm
2018/9/12
This paper discusses a prediction based workload performance evaluation implementation during Disaster Management, especially at the response phase, to handle large spatial data in the event of an eru...
Context-adaptive Pixel Based Prediction for Intra Frame Encoding
Context-adaptive Pixel Based Prediction Intra Frame Encoding
2010/6/30
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...
A 3D auto-regressive model for bidirectional prediction
3D auto-regressive model bidirectional prediction
2009/12/31
In this paper, a 3D auto-regressive (AR) model is proposed for bi-directional prediction. The prediction is composed of two 3D AR models, which are along the forward and backward directions, respectiv...

2007/12/31
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...
Selective inter-layer prediction in scalable video coding
Selective inter-layer prediction scalable video coding
2007/12/31
In the scalable video coding (SVC) standard, spatial scalable coding outperforms simulcast coding when programs with several display resolutions are needed. Nevertheless, it is not suitable for end de...
Joint coding Scheme for Maximum Macroblock Prediction
Joint coding Scheme Maximum Macroblock Prediction
2006/12/31
In this paper, a joint coding scheme for improving the coding efficiency of macroblock prediction type (MBTYPE) and coded block pattern (CBP) is proposed. The proposed coding scheme exploits the chara...

2004/12/31
In the conventional video codec, B pictures usually employ five prediction modes, including bi-prediction, direct prediction,forward prediction, backward prediction and intra modes.Among them, the dir...
Multiple Modes Intra-Prediction in Intra Coding
Multiple Modes Intra-Prediction Intra Coding
2004/12/31
Intra-prediction is a widely used technique in intra coding. In H.264 nine directional prediction modes are
used and in AVS six modes are used. This paper proposes a multiple mode intra prediction sc...
