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
UAS Ocean color Littoral waters Bottom reflectance Radiance Visible spectrum Saint Lawrence Estuary
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
