Multi-digital camera systems (MDCS) are constantly being improved to meet the increasing requirement of high-resolution spatial data. This study identifies the insufficiencies of traditional MDCSs and proposes a new category MDCS based on tilt-shift photography to improve ability of the MDCS to acquire high-accuracy spatial data. A prototype system, including two or four tilt-shift cameras (TSC...

M oday, M arch 7, 2017 reduction (SPAIR) mammaplasty. This technique utilizes an inferior pedicle, circumvertical skin resection pattern, and purse-string peri-areolar closure to achieve a stable and aesthetic breast shape. Late breast distortion from seroma formation is rare complication than may occur after an initially satisfactory result. Contraction of the seroma cavity may cause the surro...

The role played b y the distortion measure in a vector quant izat ion image encoder is very imporsuch distortion function as long as d ( X , C ) and the centroid of a set of vectors using this distortion function exists. tant. In the following paper we suggest a general class of distor t ion function, the input-dependent weighted square e r r o r distortion, which is computationally simple and ...

The aim of the current study was to determine the association between fundus fluorescein angiography (FFA) image results, optical coherence tomography (OCT) imaging results and visual functions in patients with idiopathic epiretinal membranes (ERMs). A total of 80 eyes from 40 patients diagnosed with ERM were analyzed. Best-corrected visual acuity (BCVA) and metamorphopsia were measured using t...

by analyzing the zero-field-splitting parameters and of cr2+ (3d4) ion located at tetrahedral site in znse crystal, the local structure distortion and absorption spectra around cr2+ in znse: cr2+ system have been calculated on the basis of the complete energy matrix for the d4 configuration within the strong-filed-representation. it is shown that there exists an expansion distortion in the loca...

In preparation to make the most of our own planned James Webb Space Telescope investigations, we take advantage publicly available calibration and early-science observations independently derive test a geometric-distortion solution for NIRCam detectors. Our is able correct distortion better than ∼ $$ \sim 0.2 mas. Current data indicate that stable constant over investigated filters, temporal co...

The first hypervelocity stars, bodies with radial velocities greater than the escape speed of the Milky Way, have previously been observed only in the halo of our Galaxy. However, they are thought to originate near the Galactic center. We present the most extensive search to date for hypervelocity stars in this region. Our images were taken over a one year baseline with the W. M. Keck II 10 m t...

Abstruct-Rate of convergence results are established for vector quantization. Convergence rates are given for an increasing vector dimension and/or an increasing training set size. In particular, the following results are shown for memoryless realvalued sources with bounded support at transmission rate R: (1) If a vector quantizer with fixed dimension k is designed to minimize the empirical mea...

We report a multi–dimensional quadrature amplitude modulation with M-ary differential phase shift keying (QAM-MDPSK) for optical access network transmission systems employing Mach–Zehnder modulator (MZM) and (PM) in direct detection system. Even though several problems that occur QAM-DPSK single MZM were solved, inter-signal distortion between two modulations remains when the signal is converte...
