This report is concerned with understanding the interplay between 3D face reconstruction and recognition. We provide analysis for the effect of adaptive sparse 3D reconstructions on recognition rate. This work illustrates that, for 3D face recognition, a proper mesh containing nearly 2% of the facial information and about 5 times the initial/root mesh provides similar recognition rate as one wi...

In this paper we present steps towards the automatic detection of vulnerable road users in video. Such a system can e.g. be used as an automatic blind spot camera for trucks. The aim of the system is to automatically warn the driver when the algorithm detects vulnerable road users in the camera images. Such an application implies severe time and performance constraints on the vision system, whi...

The camera calibration in monocular vision represents the relationship between pixels’ units which is obtained from a and object real world. As an essential procedure, calculates three-dimensional geometric information captured two-dimensional images. Therefore, modified method based on polynomial regression proposed to simplify. In this method, parameter vector by pixel coordinates of obstacle...

We refute the widely held belief that the quantum weak value necessarily pertains to weak measurements. To accomplish this, we use the transverse position of a beam as the detector for the conditioned von Neumann measurement of a system observable. For any coupling strength, any initial states, and any choice of conditioning, the averages of the detector position and momentum are completely des...

A prism spectrograph with an associated SIT television camera, operating as a two-dimensional detector with digital readout, has been used at the 5-m Hale telescope. The system was tested for its ability to subtract the sky spectrum, and was found to produce difference spectra that are essentially photon noise limited. Redshifts of 14 galaxies in clusters with 0.01 ::::; z ::::; 0.4 were obtain...
