Single photo and electroproduction of pions at

by B. Julia-diaz , 908
"... Within the Excited Baryon Analysis Center we have performed a dynamical coupled-channels analysis of the available p(e,e ′ π)N data in the region of W ≤ 1.6 GeV and Q 2 ≤ 1.45 (GeV/c) 2. The channels included are γ ∗ N, πN, ηN, and ππN which has π∆, ρN, and σN components. With the hadronic parameter ..."

Within the Excited Baryon Analysis Center we have performed a dynamical coupled-channels analysis of the available p(e,e ′ π)N data in the region of W ≤ 1.6 GeV and Q 2 ≤ 1.45 (GeV/c) 2. The channels included are γ ∗ N, πN, ηN, and ππN which has π∆, ρN, and σN components. With the hadronic parameters of the model determined in our previous investigations of πN → πN reaction, we have found that the available data in the considered W ≤ 1.6 GeV region can be fitted well by only adjusting the bare γ ∗ N → N ∗ helicity amplitudes for the lowest N ∗ states in P33, P11, S11 and D13 partial waves. The meson cloud effect, as required by the unitarity conditions, on the γ ∗ N →N ∗ form factors are examined. Key words meson electroproduction, helicity amplitudes PACS 13.75.Gx, 13.60.Le, 14.20.Gk 1

Single Photo Estimation of Hair Appearance

by Hendrik P. A. Lensch, Peter-pike Sloan, Nicolas Bonneel, Sylvain Paris, Michiel Van De Panne, Frédo Dur, George Drettakis
"... Significant progress has been made in high-quality hair rendering, but it remains difficult to choose parameter values that reproduce a given real hair appearance. In particular, for applications such as games where naive users want to create their own avatars, tuning complex parameters is not pract ..."

is not practical. Our approach analyses a single flash photograph and estimates model parameters that reproduce the visual likeness of the observed hair. The estimated parameters include color absorptions, three reflectance lobe parameters of a multiple-scattering rendering model, and a geometric noise parameter

Frontend Electronics for high-precision single photo-electron timing

"... The next generation of high-luminosity experiments requires excellent particle identification de-tectors, which calls for imaging Cherenkov counters with fast electronics to cope with the ex-pected hit rates. A Barrel DIRC will be used in the central region of the Target Spectrometer of the planned ..."

PANDA experiment at FAIR. A single photo-electron timing resolution of better than 100 ps RMS is required for the Barrel DIRC to disentangle the complicated patterns created on the image plane. R&D studies have been performed to provide a design based on the TRB3 readout using FPGA-TDCs with a

3-Sweep: Extracting Editable Objects from a Single Photo

by Tao Chen, Zhe Zhu, Ariel Shamir, Shi-min Hu, Daniel Cohen-or
"... full extracted 3D model. (e) Editing the model by rotating each arm in a different direction, and pasting onto a new background. The base of the object is transferred by alpha matting and compositing. We introduce an interactive technique for manipulating simple 3D shapes based on extracting them fr ..."

from a single photograph. Such extraction requires understanding of the components of the shape, their projections, and relations. These simple cognitive tasks for humans are particularly difficult for automatic algorithms. Thus, our approach combines the cognitive abilities of humans

Orientation Parameters and Reconstruction of Space Models from a Single Photo

by Mohammed Elshafei , Abdel - Latif , Ahmed A Elsonbaty , 2009
"... Abstract. Precise measurements in photogrammetry require the use of metric cameras. But they are too expensive and are not always available. Non-metric cameras are always at hand and have flexibility in focusing range. However, a non-metric camera needs to be calibrated. The determination of its or ..."
Abstract - Add to MetaCart
orientation parameters (camera position, image plane, principle point in photo and camera focal length) allows the use of the camera in many fields of photogrammetry. Previous methods used to determine the orientation parameters require at least five control points, and the solution is complicated unless

Removing camera shake from a single photograph

by Rob Fergus, Barun Singh, Aaron Hertzmann, Sam T. Roweis, William T. Freeman - ACM Trans. Graph , 2006
"... Camera shake during exposure leads to objectionable image blur and ruins many photographs. Conventional blind deconvolution methods typically assume frequency-domain constraints on images, or overly simplified parametric forms for the motion path during camera shake. Real camera motions can follow c ..."
Abstract - Cited by 325 (16 self) - Add to MetaCart
to estimate the blur from the camera shake, the user must specify an image region without saturation effects. We show results for a variety of digital photographs taken from personal photo collections.

IMPLEMENTATION OF A SINGLE PHOTO SHAPE FROM SHADING METHOD FOR THE AUTOMATIC DTM GENERATION

EN2: Graphics Audio-aware on-the-fly Animation from Single Photo

by Konstantin Kryzhanovsky, Ilia Safonov, Zoya Pushchina

Abstract - Add to MetaCart
In this paper we propose new approach of automatic generating real time content adaptive animation effects from the still images adapted for the low-powerful embedded HW platforms. Displayed animation behaves uniquely each time it’s played back, and does not repeat itself during playback duration, creating vivid and lively impression for the viewer. Adaptation of the effect parameters according to background audio greatly increases aesthetic impression of the viewer. Three animation effects such as Flashing Light, Soap Bubbles and Sunlight Spot are described in details. We propose several ways of controlling the effect parameters by music. User opinion survey demonstrates that majority of users are excited by such effects and wants to see them in their devices with multimedia capability.
