Several researches in leaf identification did not include color information as features. The main reason is caused by a fact that they used green colored leaves as samples. However, for foliage plants—plants with colorful leaves, fancy patterns in their leaves, and interesting plants with unique shape—color and also texture could not be neglected. For example, Epipremnum pinnatum ‘Aureum’ and E...

Image retrieval is an important research field, which has received great attention in the last decades. The main purpose of research in this field is to improve the process of finding the desired image in the large and variable database. In this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. For text-based features, keywo...

Recently I.) used velocity moments of a classical kinetic equation to derive a hydrody-namic description of electron motion in a degenerate electron gas. Independently , the present authors (Theochem 501-502, 327 (2000)) used considerations arising from the Harmonic Potential Theorem (Phys. Rev. Lett. 73, 2244 (1994)) to generate a new form of high-frequency hydrodynamics for in-homogeneous deg...

The closure problem for the stellar hydrodynamic equations is studied by describing the family of phase space density functions, for which the collisionless Boltzmann equation is strictly equivalent to a finite subset of moment equations. It is proven that the redundancy of the higher-order moment equations and the recurrence of the velocity moments are of similar nature. The method is based on...

With the development of multimedia technology and digital devices, it is increasingly easier to photograph a high quality image. Due to the facility of capture process, recapture phenomenon becomes popular, which is harmful sometimes. In this paper, an effective recaptured image forensics algorithm through color moments and DCT coefficients features is proposed. Central moments in chromatic spa...

S U M M A R Y The variation of frequency-dependent seismic wave attenuation with direction (attenuation anisotropy) contains additional information to that contained in velocity anisotropy. In particular, it has the potential to distinguish between different mechanisms that can cause velocity anisotropy. For example, aligned fracturing might be expected to cause measurable velocity and attenuat...

T o many people in this community, “multimedia” means multiple digitalmedia types, such as audio, images, and video. From audio/visual (AV) media, researchers can extract various AV features—for example, melfrequency cepstral coefficients (MFCC) from audio, color moments from images, or motion vectors from videos—to represent the AV multimedia. Significant research has been done in feature extr...

Point clouds acquired by RGB-D camera-based indoor mobile mapping system suffer the problems of being noisy, exhibiting an uneven distribution, and incompleteness, which are the problems that introduce difficulties for point cloud planar surface segmentation. This paper presents a novel color-enhanced hybrid planar surface segmentation model for RGB-D camera-based indoor mobile mapping point cl...

Using cosmological N -body simulations we study the radial velocity distribution in dark matter haloes focusing on the lowest-order even moments, dispersion and kurtosis. We determine the properties of ten massive haloes in the simulation box approximating their density distribution by the NFW formula characterized by the virial mass and concentration. We also calculate the velocity anisotropy ...

We introduce a new approach to prove the regularity of solutions to transport equations of the Vlasov type. Our approach is mainly based on the proof of propagation of velocity moments, as in a previous paper by Lions and Perthame [16]. We combine it with Moment Lemmas which assert that, locally in space, velocity moments can be gained from the kinetic equation itself. We apply our theory to tw...
