PolInSAR Tree Canopy Height Random Volume over Ground UAVSAR AfriSAR coherence
2019/2/28
Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) technique utilizes the characteristics of both SAR polarimetry and Interferometry. PolInSAR technique is proved to be very useful for v...
ACCURACY ESTIMATION OF THE OPTICAL FLOWMETHODS IN THE IRIS STRUCTURE MOTION ANALYSIS VIA CONTROLLED DEFORMATIONS
Biometrics Iris Structure Computer Vision Image Analysis Optical Flow Horn-Schunck Method Lucas-Kanade Method Accuracy Estimation
2017/6/19
The iris structure motion is analyzed. Extension and compression of the iris structural elements are nonlinear with respect to the pupil radius change. To reveal this nonlinearity the Lucas-Kanade, Ho...
PIXEL-BY-PIXEL ESTIMATION OF SCENE MOTION IN VIDEO
video sequence image processing moving object detection tracking recurrent procedures reverse processing
2017/6/19
The paper considers the effectiveness of motion estimation in video using pixel-by-pixel recurrent algorithms. The algorithms use stochastic gradient decent to find inter-frame shifts of all pixels of...
CONVOLUTIONAL NEURAL NETWORK FOR CAMERA POSE ESTIMATION FROM OBJECT DETECTIONS
Camera Pose CNN Head Detection Computer Graphics
2017/6/19
Known scene geometry and camera calibration parameters give important information to video content analysis systems. In this paper, we propose a novel method for camera pose estimation based on people...
Achieving the WHO sodium target: estimation of reductions required in the sodium content of packaged foods and other sources of dietary sodium
sodium salt WHO target chronic disease
2018/12/13
Background: Excess sodium intake is one of the top 2 dietary risk factors contributing to the global burden of disease. As such, many countries are now developing national sodium reduction strategies,...
Model-Based Motion Estimation for Synthetic Animations
Synthetic Animations Model-Based Motion
2016/5/24
One approach to performing motion estimation on synthetic
animations is to treat them as video sequences
and use standard image-based motion estimation methods.
Alternatively, we can take advantage...
Heterogeneous Income Profi les and Lifecycle Bias in Intergenerational Mobility Estimation
Lifecycle Bias Intergenerational Mobility Estimation
2016/3/2
Using short snapshots of income in intergenerational mobility estimation
causes “lifecycle bias” if the snapshots cannot mimic lifetime outcomes.
We use uniquely long series of Swedish income data...
Estimation of a Tax Gap in the Personal Income Tax by Means of National Accounts
Czech Republic National Accounts Personal Income Tax Tax Gap
2016/1/27
The article deals with the estimation of a tax gap incurred by devastation of a tax base and concentrates on undervaluation of incomes from an independent activity. The distortion rate was estimated b...
