Separating the diffuse and specular components from the reflection of a 3D object surface is very important for generating highly realistic synthesized images in computer graphics applications. Most research on this separation has considered only the case in which an object is illuminated by a single point light source. However, when an object is illuminated by one source, it can be difficult o...

Introduction Dixon methods do not only provide a more robust fat suppression in the presence of field inhomogeneity than selective saturation and excitation methods, but also promise a more complete fat suppression, when multi-peak spectral models of fat are employed in the separation. The latter has convincingly been demonstrated for a three-point method lately [1]. In this work, such models a...

PURPOSE To relate vocal fold structure and kinematics to 2 acoustic measures: cepstral peak prominence (CPP) and the amplitude of the first harmonic relative to the second (H1-H2). METHOD The authors used a computational, kinematic model of the medial surfaces of the vocal folds to specify features of vocal fold structure and vibration in a manner consistent with breathy voice. Four model par...

We develop a reduced-order model for large-scale unsteadiness (vortex shedding) in a two-dimensional diffuser and use the model to show how periodic mass injection near the separation point reduces stagnation pressure loss. The model estimates the characteristic frequency of vortex shedding and stagnation pressure loss by accounting for the accumulated circulation due to the vorticity flux into...

killifish (aphanius sophiae) of the cheshme-ali of damghan and shour river of eshteherd were studied and compared from morphological point of view. for morphometric studies, 34 truss morphometric measurements and  10 traditional  measurements  were made for each individual. nine meristic traits were counted. multi-variate analysis of variance (manova) revealed a significant different between va...

The accurate leaf-wood separation of individual trees from point clouds is an important yet challenging task. Many existing methods rely on manual features that are time-consuming and labor-intensive to distinguish between leaf wood points. However, due the complex interlocking structure leaves in canopy, these have not yielded satisfactory results. Therefore, this paper proposes end-to-end LWS...
