PATHWAY DETECTION AND GEOMETRICAL DESCRIPTION FROM ALS DATA IN FORESTED MOUNTANEOUS AREA
lidar road feature extraction vectorization mapping mountainous areas
2016/2/29
In the last decade, airborne laser scanning (ALS) systems have become an alternative source for the acquisition of altimeter data.
Compared to high resolution orthoimages, one of the main advantages ...
Efficient Multiple-Description Image Coding Using Directional Lifting-Based TransformEfficient Multiple-Description Image Coding Using Directional Lifting-Based Transform
Efficient Multiple-Description Image Coding Directional Lifting-Based
2010/12/17
This paper proposes an efficient two-description image coding technique. The two side descriptions of an image are generated by quincunx subsampling. The decoding from any
side description is done by...
Exciting Event Detection in Broadcast Soccer Video with Mid-level Description and Incremental Learning
Exciting Event Detection Broadcast Soccer Video Mid-level Description
2010/12/15
In this paper, we propose a method for exciting event detection in broadcast soccer video with mid-level description and SVM-based incremental learning. In the method, video frames are firstly classif...
Embedded Packetization Framework for Layered Multiple Description Coding
Embedded Packetization Framework Layered Multiple Description Coding
2010/12/14
We present an embedded packetization framework for layered multiple description codes, in which both the base layer and the enhancement layer share the same number of packets, while each packet is par...
FEC-based Multiple Description Coding for Heterogeneous Client Bandwidths
FEC-based Multiple Description Coding Heterogeneous Client Bandwidths
2010/12/14
We consider applying the FEC-based multiple description coding method for multicasting a source to a
set of clients with heterogeneous access bandwidths. In the scenario where different clients acce...

Quality Smoothing FEC-based Multiple Description Coding
2010/12/14
When sending a scalable video sequence over packet loss channels, one usually partitions it into groups of frames
(GOFs), and protects each GOF using the FEC based multiple description coding (FEC-MD...
Neutral atmospheric delay in interferometric synthetic aperture radar applications: Statistical description and mitigation
Neutral atmospheric delay in interferometric synthetic aperture radar applications Statistical description mitigation
2014/4/9
Variations in the refractive index of the atmosphere cause variations in satellite-based interferometric synthetic aperture radar (InSAR) observations. We can mitigate tropospheric effects by averagin...
