We present recent developments in double machine learning (DML) approach. The DML approach is concerned primarily with selecting the relevant control variables and functional forms necessary for the c...
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...
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...
We investigate the asymptotic relationship between quantum cloning and quantum estimation from the global point of view where all the copies produced by the cloner are considered jointly.For an N-to-M...
Integer parameter estimation in linear models with applications to GPS
Integer parameter estimation Linear model Integer least-squares GPS
2015/8/11
We consider parameter estimation in linear models when some of the parameters are known to be integers. Such problems arise, for example, in positioning using phase measurements in the global position...

Distributed framework convex optimization sensor networks signal processing subsystem sensor subsystem distributed estimation algorithm
2015/8/10
The focus of this paper is to develop a framework for distributed estimation via convex optimization. We deal with a network of complex sensor subsystems with local estimation and signal processing. M...
An Ionosphere Estimation Algorithm for WAAS Based on Kriging
Ionosphere Estimation Algorithm WAAS Based Kriging
2015/6/26
GPS alone cannot provide the integrity needed for air navigation. Several error sources deteriorate the precision of the position estimate. One of the largest and more unpredictable sources of error f...
A New Ionospheric Estimation Algorithm for SBAS Combining Kriging and Tomography
Ionospheric Estimation Algorithm SBAS Combining Kriging Tomography
2015/6/26
One can divide the existing ionospheric methods for SBAS in two categories: tomography and methods relying on the thin shell model. At first sight, tomography appears to be the right choice. Tomograph...
CMOS feature size scaling has been a source of dramatic performance gains, but it has come at a cost of on-chip wear-out. Negative Bias Temperature Instability (NBTI) is one of the main on-chip wear-o...
