Detection of the best symmetry plane in 3D images can be treated as a registration problem between the original and the reflected images. The registration is performed in a 3D space of parameters defining orientation and shift of a reflection plane. We use the normalized metric as the similarity measure between original and reflected images and investigate an algorithm for computation of the be...

The tangent plane algorithm is a fast sequential learning method for multilayered feedforward neural networks that accepts almost zero initial conditions for the connection weights with the expectation that only the minimum number of weights will be activated. However, the inclusion of a tendency to move away from the origin in weight space can lead to large weights that are harmful to generali...

It is difficult to estimate the midsagittal plane of human subjects with craniomaxillofacial (CMF) deformities. We have developed a LAndmark GEometric Routine (LAGER), which automatically estimates a midsagittal plane for such subjects. The LAGER algorithm was based on the assumption that the optimal midsagittal plane of a patient with a deformity is the premorbid midsagittal plane of the patie...

We provide a design of clean-slate control and management plane for data networks using the abstraction of 4D architecture, utilizing and extending 4D’s concept of a logically centralized Decision plane that is responsible for managing network-wide resources. In this paper, a scalable protocol and a dynamically adaptable algorithm for assigning Data plane devices to a physically distributed Dec...

The rapid rise in popularity of multimedia applications, such as VoIP, IPTV and Video Conferencing, intensifies the need to consider resource management for user satisfaction. Furthermore, improving Quality of Experience (QoE) in Software Defined Networks (SDNs) services is one of the important issues to be addressed by provisioning optimum resource management. In this paper, resource allocatio...

A disk Wang-Bézier type generalized Ball curve is a Wang-Bézier type generalized Ball curve whose control points are disks in a plane. It can be viewed as a parametric curve with error tolerances. In this paper, we discuss the problem of degree reduction of disk Wang-Bézier type generalized Ball curve, that is, bounding disk Wang-Bézier type generalized Ball curves with lower degree disk Wa...

In this paper, we present a survey on management mechanisms used for ensuring the Quality-of-Services for Voice-over-IP applications. We first address the motivations of QoS management for VoIP. We then partition the system into two management planes: data plane and control plane, and describe mechanisms in each plane respectively. In data plane, we cover several important techniques including ...

An analysis of a rasterization algorithm for generating supercover planes in 3D voxel space is presented. The derived algorithm is an extension to the classical 2D line rasterization algorithm. Additional voxels needed to form the supercover 3D plane are identified by rasterizing two additional 2D lines per volume slice. A discussion on how to modify the algorithm to rasterize finite supercover...

In this paper, we are concerned with the weighted plane wave least-squares (PWLS) method for three-dimensional Helmholtz equations, and develop multi-level adaptive BDDC algorithms solving resulting discrete system. order to form coarse components, local generalized eigenvalue problems each common face edge carefully designed. The condition number of two-level preconditioned system is proved be...
