1-(Butan-2-ylidene)-2-(2-nitrophenyl)hydrazine
Crystals of the title compound, C10H13N3O2, were obtained from a condensation reaction of butan-2-one and 1-(2-nitrophenyl)hydrazine. The molecule exhibits a nearly coplanar structure, except for the methyl and methylene H atoms, the largest deviations from the mean plane defined by all non-H atoms, except for the nitro group, being 0.120 (2) Å for one of the nitro O atoms. Intramolecular N—H⋯O hydrogen bonding helps to establish the molecular configuration
N′-(2-Furylmethylene)nicotinohydrazide
The asymmetric unit of the title compound, C11H9N3O2, contains two independent molecules: the dihedral angles between the pyridine ring and the furyl ring are 17.00 (16) and 34.12 (15)°. The crystal structure involves intermolecular C—H⋯O, N—H⋯N and N—H⋯O hydrogen bonds
{4-Bromo-2-[3-(diethylammonio)propyliminomethyl]phenolato}diiodidozinc(II) methanol solvate
In the title complex, [ZnI2(C14H21BrN2O)]·CH3OH, the asymmetric unit consists of a mononuclear zinc(II) complex molecule and a methanol solvent molecule. The compound was derived from the zwitterionic form of the Schiff base 4-bromo-2-[3-(diethylamino)propyliminomethyl]phenol. The ZnII atom is four-coordinated by the imine N and phenolate O atoms of the Schiff base ligand and by two iodide ions in a distorted tetrahedral coordination. In the crystal structure, the methanol molecules are linked to the Schiff base molecules through N—H⋯O and O—H⋯O hydrogen bonds. One I atom is disordered over two positions in a 0.702 (19):0.298 (19) ratio
{4-Bromo-2-[2-(piperidin-1-ium-1yl)ethyliminomethyl]phenolato}diiodidozinc(II)
In the title complex, [ZnI2(C14H19BrN2O)], the ZnII atom is four-coordinated by the imine N and phenolate O atoms of the Schiff base ligand and by two iodide ions in a distorted tetrahedral coordination. In the crystal structure, molecules are linked through intermolecular N—H⋯O hydrogen bonds, forming chains running along the b axis
Diiodido[N′-(2-methoxybenzylidene)-N,N-dimethylethane-1,2-diamine]zinc(II)
In the title complex, [Zn(C12H18N2O)I2], the ZnII ion is four-coordinated by the imine N and amine N atoms of the Schiff base ligand and by two iodide ions in a distorted tetrahedral coordination
Realtime reconstruction of an animating human body from a single depth camera
We present a method for realtime reconstruction of an animating human body, which produces a sequence of deforming meshes representing a given performance captured by a single commodity depth camera. We achieve realtime single-view mesh completion by enhancing the parameterized SCAPE model. Our method, which we call Realtime SCAPE, performs full-body reconstruction without the use of markers. In Realtime SCAPE, estimations of body shape parameters and pose parameters, needed for reconstruction, are decoupled. Intrinsic body shape is first precomputed for a given subject, by determining shape parameters with the aid of a body shape database. Subsequently, per-frame pose parameter estimation is performed by means of linear blending skinning (LBS); the problem is decomposed into separately finding skinning weights and transformations. The skinning weights are also determined offline from the body shape database, reducing online reconstruction to simply finding the transformations in LBS. Doing so is formulated as a linear variational problem; carefully designed constraints are used to impose temporal coherence and alleviate artifacts. Experiments demonstrate that our method can produce full-body mesh sequences with high fidelity
1-(But-2-enylidene)-2-(2-nitrophenyl)hydrazine
The molecule of the title Schiff base compound, C10H11N3O2, adopts an E geometry with respect to the C=N double bond. The molecule is roughly planar, with the largest deviation from the mean plane being 0.111 (2) Å, The enylidene-hydrazine group is, however, slightly twisted with respect to the phenyl ring, making a dihedral angle of 6.5 (3)°. An intramolecular N—H⋯O hydrogen bond may be responsible for the planar conformation. An intermolecular N—H⋯O hydrogen bond links two molecules around an inversion center, building a pseudo dimer
Diiodido{4-nitro-2-[2-(piperidin-1-yl)ethyliminomethyl]phenolato}zinc(II)
In the title complex, [ZnI2(C14H19N3O3)], the ZnII atom is four-coordinated by the imine N and phenolate O atoms of the Schiff base ligand, and by two iodide ions in a distorted tetrahedral coordination. In the crystal structure, molecules are linked through intermolecular N—H⋯O hydrogen bonds, forming dimers
2-Ethoxy-4-{[(2-nitrophenyl)hydrazono]methyl}phenol
The title compound, C15H15N3O4, a Schiff base, was obtained from a condensation reaction of 3-ethoxy-4-hydroxybenzaldehyde and 2-nitrophenylhydrazine. The molecule is approximately planar, the largest deviation from the mean plane being 0.1449 (16) Å. An intramolecular N—H⋯O interaction is also present. In the crystal, intermolecular O—H⋯O hydrogen bonds link the molecules, forming chain parallel to the b axis
