CVABS: Moving Object Segmentation with Common Vector Approach for Videos

Background modelling is a fundamental step for several real-time computer vision applications that requires security systems and monitoring. An accurate background model helps detecting activity of moving objects in the video. In this work, we have developed a new subspace based background modelling algorithm using the concept of Common Vector Approach with Gram-Schmidt orthogonalization. Once the background model that involves the common characteristic of different views corresponding to the same scene is acquired, a smart foreground detection and background updating procedure is applied based on dynamic control parameters. A variety of experiments is conducted on different problem types related to dynamic backgrounds. Several types of metrics are utilized as objective measures and the obtained visual results are judged subjectively. It was observed that the proposed method stands successfully for all problem types reported on CDNet2014 dataset by updating the background frames with a self-learning feedback mechanism.Comment: 12 Pages, 4 Figures, 1 Tabl

2-Chloro-4-{(E)-[(4-chloro­phen­yl)imino]­meth­yl}phenol

In the title Schiff base compound, C13H9Cl2NO, the dihedral angle between the mean planes of the benzene rings is 10.20 (10)°. The crystal structure is stabilized by O—H⋯N hydrogen bonds and weak π–π stacking inter­actions [centroid–centroid distance = 3.757 (1) Å]

The Cult of Demos and Personification

DergiPark: 326241trakyasobedThe word of Demos has different meanings in and these meanings were not distinguished from one another precisely Greek language. The people or a section of the people, people assembly, a democratic regime, and village, all of them have the meaning of the demos. Athenians belived that their own regime was original and constituted a model to other regimes. As a result of these considerations “The Cult of Demos” was born in Athens. The Cult of Demos has been worshipped outside of the Athenian Agora with Nymphs since fifth century BC. and “The Cult of Demos and Charites” has been established in the third century BC. in Athens. Demos was seen probably first time as a character in Aristophanes’ Knights in 424 BC. It is the last quarter of the fifth century BC. that the first known personification of Demos in visual arts was created in a painting by Parrhasios, fallowed by the ones of Euphranor and Aristolaos.Demos sözcüğü Grekçede farklı anlamlar içerir ve bu anlamlar kesin bir şekilde birbirlerinden ayrılmamaktadır. Halk ya da halkın bir bölümü, halk meclisi, demokratik bir rejim ve köy tüm bunların hepsi demos anlamındadır. Atinalılar kendi yönetim şekillerinin özgün olduğuna ve diğer yönetimlere model oluşturduğuna inanıyorlardı. Bu düşüncelerin sonucunda Atina’ da Demos Kültü doğmuştur. Atina Agorasının dışında Nympheler Kültü ile birlikte, MÖ. 5. yüzyıldan itibaren “Demos Kültü” tapım görmüş ve MÖ. 3. yüzyılda Atina’ da, “Demos ve Kharitler Kutsal Alanı” oluşturulmuştur. Demos bir karakter olarak olasılıkla ilk kez MÖ. 424 yılında Aristophanes’ in “Şövalyeler” oyununda görülmüştür. Görsel sanatlarda demosun bilinen ilk personifikasyonu MÖ. 5 yüzyılın son çeyreğinde Atina Agorası’ ndaki Parrhasios’ un resmidir. Bunu Euphranor ve Aristolaos’ un resimleri izle

Zeus Cult in Aegean Thrace By Epigraphic Evidence

DergiPark: 371211trakyasobedBu çalışmada -epigrafikbelgelerden yararlanarak- Ege Trakyası’ndaki Zeus kültleri ve bölgeler arası etkileşimiincelenmiştir. İncelenen yazıtların buluntu yerleri bölgenin önemli kıyı yerleşimlerindenAbdera, Stryme, Maroneia, Ainos ve kara yerleşimlerinden Agiasma vePesoule-Maksimianoupolis’dir. Zeus bölgede,  MÖ. 5. yüzyılın 2. yarısı ile MS. 4. yüzyılarasında, tek başına veya Athena, Dionysos,Kral Philippos, Maron ve Tanrıça Roma ile birleştirilerek tapım görmüştür. Orios, Eleutherios, Zbelthiourdos, Pesoulenos ve Hypsistos –kronolojik olarak- bölgede kullanılan Zeusepithetleridir.In this study, thecults of Zeus and its interaction between the regions was investigated in theAegean Thrace by using the epigraphic evidences. Theseinscriptions were found in Abdera, Stryme, Maroneia and Ainos which wereimportant coastal settlements and in Agiasma and Pesoule-Maksimianoupolis whichwere land settlements of  theregion.Zeus was worshiped alone or combined with another deity-Athena, Dionysos, King Philippos, Maron and goddess Rome- betweenthe 2nd half of the 5th century BC. and the 4th century AD. Orios, Eleutherios, Zbelthiourdos, Pesoulenosand Hypsistos are epithets ofZeus used in the region

(E)-2-[3-(Trifluoro­meth­yl)phenyl­imino­meth­yl]benzene-1,4-diol

In the title compound, C14H10F3NO2, the two benzene rings are oriented at a dihedral angle of 31.94 (14)°. An intra­molecular O—H⋯N hydrogen bond helps to stabilize the mol­ecular structure. In the crystal, inter­molecular O—H⋯O hydrogen bonding links the mol­ecules, forming chains running along the crystallographic a axis. The F atoms of the trifluoro­methyl group are disordered over two positions with refined site occupancies of 0.488 (5) and 0.512 (5)

(E)-2-[(2,4-Dichloro­phen­yl)imino­meth­yl]benzene-1,4-diol monohydrate

The title compound, C13H9Cl2NO2·H2O, represents a Schiff base which adopts the phenol–imine tautomeric form in the solid state. The mol­ecule is approximately planar (r.m.s. deviation 0.0818 Å), and the dihedral angle between the two aromatic rings is 7.46 (12)°. An O—H⋯N inter­action generates an S(6) ring. In the crystal, mol­ecules are linked by inter­molecular O—H⋯O hydrogen bonds involving the solvent water mol­ecule, forming chains

(E)-2-[(2,4-Dichloro­phen­yl)imino­methyl]-6-methyl­phenol

The title compound, C14H11Cl2NO, is a Schiff base which adopts the phenol–imine tautomeric form in the solid state. There are two mol­ecules in the asymmetric unit. Head-to-tail π–π inter­actions [centroid-to-centroid distances of 3.682 (2), 3.708 (2), 3.904 (2) and 3.910 (2) Å] between adjacent mol­ecules produce two symmetry-independent infinite chains running along the b axis

Cost analysis and related factors in patients with traumatic hand injury

The aim of this study was to measure the direct and indirect costs and factors influencing these costs in patients presenting following traumatic hand injury. We assessed patients aged 18-65 years who were in work. Hand injury severity and functional status were assessed. Direct costs, including medical care expenses, and indirect costs, including lost productivity, were calculated. Seventy-nine patients of a mean age of 32 years were included. The mean direct cost for each patient was $1772 (47$1891 (53% of total cost). Injury severity, time to return to work, and hospitalization time were the main parameters of increased total cost in a linear regression analysis. © The Author(s) 2012
