OPTIMAL IMAGE STITCHING FOR CONCRETE BRIDGE BOTTOM SURFACES AIDED BY 3D STRUCTURE LINES
Image Stitching 3D Structure Line Concrete Bridge Inspection
2016/7/27
Crack detection for bridge bottom surfaces via remote sensing techniques is undergoing a revolution in the last few years. For such applications, a large amount of images, acquired with high-resolutio...
A COMPUTATIONAL METHOD TO EMULATE BOTTOM-UP ATTENTION TO REMOTE SENSING IMAGES
Image interpretation Modelling Image understanding Texture Analysis Process modelling
2015/12/23
In this paper, we propose a computational model which is capable of emulating the expert’s bottom-up attention to remote sensing images. The bottom-up visual attention is a relatively primary step in ...
A NEW TECHNIQUE BASED ON MINI-UAS FOR ESTIMATING WATER AND BOTTOM RADIANCE CONTRIBUTIONS IN OPTICALLY SHALLOW WATERS

2015/9/10
The mapping of nearshore bathymetry based on spaceborne radiometers is commonly used for QC ocean colour products in littoral waters. However, the accuracy of these estimates is relatively poor with r...
Pca based on bottom classification applied in remote sensing bathymetry of shallow seawat
Multi-spectral Remote sensing Bathymetry model,
2015/8/20
The submarine terrain in shallow sea is one of the important factors of the ocean environment, and has important meanings for
coastal economics and military activities. For the mapping of the vast in...
Bottom Topography Observation in the Intertidal Zone Using the Camera Monitoring System
Orthoimage Monitoring Bathymetry Measurement Change Detection Oceanography
2015/7/30
The intertidal zone is characterized by periodic exposures to water level changes between high and low tides. Time series of
waterline changes during a flood/ebb cycle can be utilized for supplement...
Connections Between Ocean Bottom Topography and Earth's Climate
Ocean Bottom Topography Earth's Climate
2015/7/29
The seafloor is one of the critical controls on the ocean's general circulation. Its influence comes through a variety of mechanisms including the contribution of mixing in the ocean's interior throug...
SHALLOW-WATER BATHYMETRY OVER VARIABLE BOTTOM TYPES USING MULTISPECTRAL WORLDVIEW-2 IMAGE
Multispectral Bathymetry Linear Regression Radiometric Correction GPS Echo Sounder
2014/4/29
Image processing techniques that involve multispectral remotely sensed data are considered attractive for bathymetry applications as they provide a time- and cost-effective solution to water depths es...
A BOTTOM-UP GEOSPTIAL DATA UPDATE MECHANISM FOR SPATIAL DATA INFRASTRUCTURE UPDATING
: Geography Vector Integration Matching
2014/4/28
Currently, the top-down spatial data update mechanism has made a big progress and it is wildly applied in many SDI (spatial data
infrastructure). However, this mechanism still has some issues. For e...
Determination of water depth with high-resolution satellite imagery over variable bottom types
Determination of water depth high-resolution satellite imagery variable bottom types
2014/5/19
A standard algorithm for determining depth in clear water from passive sensors exists; but it requires tuning of five parameters and does not retrieve depths where the bottom has an extremely low albe...
