DENOISING POINT CLOUD DATA OF SMALL-STRUCTURED FREE FORMSURFACES CAPTURED BY A PHASE-BASED LASERSCANNER
Laser scanning Close-range Point Cloud Filtering Cultural Heritage
2016/2/29
Terrestrial laser scanners based on the time-of-flight measurement principle or the phase comparison method are used for cultural
heritage documentation. Only if the scanned surfaces consist of exte...
Synthesis of High Dynamic Range Motion Blur Free Image From Multiple Captures
CMOS image sensor dynamic range extension motion blur restoration motion detection photocurrent estimation saturation detection
2015/8/12
Advances in CMOS image sensors enable high-speed image readout, which makes it possible to capture multiple images within a normal exposure time. Earlier work has demonstrated the use of this capabili...
The free recall search process introduces errors in short term memory but apparently not in long term memory
short term memory memory search memory errors long term memory
2015/7/22
Here it is reported that the free recall search process increases the error rate for short term memory (about 1% per second in data from Murdock & Okada (1970)) but not for long term memory (in data f...
EXTRACTING 3D FREE-FORM SURFACE BOUNDARIES OF MAN-MADE OBJECTS FROM MULTIPLE CALIBRATED IMAGES: A ROBUST, ACCURATE AND HIGH RESOLVING POWER EDGEL MATCHING AND CHAINING APPROACH
Photogrammetry 3D Reconstruction
2015/5/18
This paper describes a purely geometrical approach for matching and chaining edgels, i.e. contours points with their tangent direction,
to reconstruct in a general way 3D rectilinear or curved surfac...
Discrimination between Ictal and Seizure-Free EEG Signals Using Empirical Mode Decomposition
Ictal Seizure-Free EEG Signals Empirical Mode Decomposition
2009/9/4
A new method for analysis of electroencephalogram (EEG) signals using empirical mode decomposition (EMD) and Fourier-Bessel (FB) expansion has been presented in this paper. The EMD decomposes an EEG s...
A Virtual View Generation Method for Free-Viewpoint Video System
View Generation Method Free-Viewpoint Video System
2010/12/16
Generating virtual views is one of the crucial problems for a free-viewpoint video system. In this paper, we solve the problem by using a method based on the technique of view
morphing, and construct...
Drift-Free Switching of Compressed Video Bitstreams at Predictive Frames,
Compressed Video Bitstreams Predictive Frames
2010/12/15
Two schemes are proposed to efficiently compress video contents into bitstreams that support drift-free switching at predictive frames. They are inspired by the original SP coding
scheme presented in...
Free viewpoint switching in multi-view video streaming using Wyner-Ziv video coding
multi-view video streaming Wyner-Ziv video coding
2010/12/16
The free viewpoint switching is one of the most important features of multi-view video streaming. The key problem lies in how to achieve the best performance when the camera processing capability and ...
Facial Feature Tracking Combining Model-Based And Model-Free Method,
Facial Feature Model-Based Model-Free Method
2010/12/14
In this paper we propose a novel facial feature tracker,which integrates model-free and model-based method to
reliably track dense facial features with complex non-rigid motions in low quality video ...
