OPTICAL FLOW APPLIED TO TIME-LAPSE IMAGE SERIES TO ESTIMATE GLACIER MOTION IN THE SOUTHERN PATAGONIA ICE FIELD
optical flow time-lapse imagery motion detection glacier
2016/11/30
In this work, we assessed the feasibility of using optical flow to obtain the motion estimation of a glacier. In general, former investigations used to detect glacier changes involve solutions that re...
MULTI-TEMPORAL DEM MATCHING METHOD WITHOUT CONTROL POINTS IN DEBRIS-FLOW AREA
Photogrammetry Geomorphology Multitemporal Change Detection Matching Accuracy Precision
2015/12/29
Detecting the volume change of loose deposit of rock debris accumulated and debris discharged is one of the methods to study debris flow. The volume can be resulted by overlapping multi-temporal DEM. ...
APPLICATION OF AERIAL VIDEO FOR TRAFFIC FLOW MONITORING AND MANAGEMENT
Remote sensing data aerial data source data acquisition image processing remote sensing data monitoring automatic image processing
2015/5/13
Researchers at the University of Arizona are investigating the potential of remotely sensed data, using aerial
video, to enhance existing data sources and therefore to improve traffic management. Thi...
QUANTIFYING GENE FLOW FROM OILSEED RAPE TO ITS WILD RELATIVES USING REMOTE SENSING (LANDSAT TM)
Gene gene flow sports population crop wild swap genes genetically modified
2015/5/13
Gene flow is defined as the movement of genes between populations and is a naturally occurring phenomenon
among sexually compatible individuals. Crops have exchanged genes with their wild and weedy ...
Mapping the Surface of Sheet Flow Water in the Everglades
Mapping Airborne Laser Intensity Nadir Points Sheet Flow Water
2015/3/10
University of Florida (UF) researchers used airborne laser swath mapping (ALSM) to map the height of vegetation, relative to the surface of sheet flow water, in the Everglades. In less than three hour...
A Comparative Study on Gradient-Based Approaches for Optical Flow Estimation
Optical Flow Analysis Movement Detection Object Tracking Image Sequence Measurement Image Processing Computer Vision
2015/1/6
The most readily available motion parameter from sequential image is optical flow. Among various optical flow estimation techniques, gradient-based approach is a common technique. This approach is bas...
AUTOMATIC STEREO MATCHING USING OPTICAL FLOW FOR 3D OBJECT MODELING
Optical Flow 3D Object Modeling Stereo Matching Coplanarity Condition Line Tracking Sequential Images
2015/1/6
In order to acquire 3D spatial data for objects using stereo image, stereo matching such as SSDA, area based matching and so on have been proposed. However, there are some issues for efficient 3D obje...
Exploiting Satellite Focal Plane Geometry for Automatic Extraction of Traffic Flow from Single Optical Satellite Imagery
Optical Satellite Data Focal plane assembly Traffic detection Moving objects detection
2014/12/4
The focal plane assembly of most pushbroom scanner satellites is built up in a way that different multispectral or multispectral and panchromatic bands are not all acquired exactly at the same time. T...
Coupling a SVAT heat and water flow model, a stomatal-photosynthesis model and a crop growth model to simulate energy, water and carbon fluxes in an irrigated maize ecosystem
Arid regions Irrigated maize Energy–water–carbon cycle Crop growth
2013/9/2
Irrigation is practiced on approximately 20% of the agricultural land in the world and accounts for approx-imately 40% of the total crop production. However, with ...
