Humans have always sought to achieve aesthetics in art. In this paper, we present a novel approach for retargeting images to different aspect ratios while improving the composition aesthetics of the results. A simpler computational aesthetic energy is proposed and used to drive the salient objects and prominent lines to move towards their corresponding optimal positions. A mesh-based warping sc...

The amount of geometric information that must be transferred between a CAD system and a computerized numerical control system creates a conflict between part precision on the one hand and feedrate fidelity and communications load on the other. This is the motivation for the development of new curve interpolation algorithms for CNC. The interpolation dependson the method of curve representation,...

This thesis is an investigation of the possibilities of realtime surgical simulation, specifically within the domain of congenital heart diseases. The problem domain of surgery on the heart of an infant is presented and the primary information necessary for a pre-operative surgical simulation tool is identified. Through cooperation with surgeons, domain specific abstractions and simplifications...

The evolution of new networking protocols has shown, that the conventional traffic models like Poisson are in many cases not suited for simulating real network behaviour [4]. This is especially true for ATM networks, because they will show a high complexity in their data rate dynamic due to statistical multiplexing of data, audio and video traffic. On the other hand realistic traffic models are...

We present a solution for realtime tracking of a planar pattern. Tracking is seen as the estimation of a parametric function between observations and motion and we propose an extension of the learning based approach presented simultaneously by Cootes and al. and by Jurie and Dhome. We show that the hyperplane classic algorithm is a specific case of a more generic linearly-weighted sum of fixed ...

BACKGROUND The Abbott RealTime High Risk HPV test (RealTime) is a novel assay designed to detect 14 high-risk human papillomavirus genotypes (hr-HPV) and concurrently distinguish HPV-16 and HPV-18 from other hr-HPV within a single test. OBJECTIVE To evaluate analytical specificity and clinical sensitivity for cervical carcinoma and cervical intraepithelial neoplasia grade 3 (CIN3) of the Real...

Bursty traffic causes excessive queuing delay and packet losses. Many researchers have proposed the modeling of burstiness and burstiness mitigation schemes. However, there is no consensus on a quantitative definition of burstiness. In this paper, burstiness is defined as the queue size of a virtual bottleneck buffer. This definition is based on the fact that packets are queued when there is a ...

This paper presents a method for real-time rendering of a neocortical column in the mouse brain with 10000 individually simulated neurons, as implemented in the software GabrielStudio (TM). It also presents how the same system is used to create movie sequences of scripted camera keyframes for high resolution outputs. The current system is running on an SGI Altix Prism Extreme with 16 parallel g...

Modern search engines feature real-time indices, which incorporate changes to content within seconds. As search engines also cache search results for reducing user latency and back-end load, without careful real-time management of search results caches, the engine might return stale search results to users despite the efforts invested in keeping the underlying index up to date. A recent paper p...

-The real time properties of traditional Ethernet are poor. The end-to-end latency through an Ethernet network based on thin Ethernet (coax 10BASE-2) or hubs (10BASE or 100BASE) depends on the network load. The non deterministic property of the Carrier Sense Multiple Access – Collision Detection (CSMA/CD) scheme has been the main argument against Ethernet as the communication solution for appli...
