Video object segmentation is an important pre-processing task for many video analysis systems. To achieve the requirement of real-time video analysis, hardware acceleration is required. In this paper, after analyzing existing video object segmentation algorithms, it is found that most of the core operations can be implemented with simple morphology operations. Therefore, with the concepts of mo...

In this paper, a simple and reliable procedure of stochastic computation is combined with the highly accurate and efficient Trefftz Computational Grains (TCG), for a direct numerical simulation (DNS) of heterogeneous materials with microscopic randomness. Material properties of each material phase, and geometrical properties such as particles sizes and distribution, are considered to be stochas...

elements for normal bodily maintenance, growth, and reproduction. Minerals that are required in relatively large amounts are called major or macro elements. Those needed in small amounts are classified as micro, minor, or trace minerals. These terms, however, have no relationship to the metabolic importance of a mineral in the diet. A trace mineral can be as essential to the health and performa...

Assertions, even as simple as the C assert macro, o er important self-checking properties to programs, and improve the robustness of software when they are used. This paper describes AsserTcl, an assertion package for the Tcl programming language. Our assertions take the form of commands in the program text, and cover point assertions about the computation state, assertions about procedure inpu...

Macro-elements of arbitrary smoothness are constructed on Powell-Sabin triangle splits. These elements are useful for solving boundaryvalue problems and for interpolation of Hermite data. It is shown that they are optimal with respect to spline degree, and we believe they are also optimal with respect to the number of degrees of freedom. The construction provides local bases for certain supersp...

A natural mixed-element approach for the Stokes equations in the velocity-pressure formulation would approximate the velocity by continuous piecewise-polynomials and would approximate the pressure by discontinuous piecewise-polynomials of one degree lower. However, many such elements are unstable in 2D and 3D. This paper is devoted to proving that the mixed finite elements of this Pk-Pk−1 type ...

Two samples, water extract and blended whole leaves, of fresh Kalanchoe integra leaves (Crassulaceae), a traditional antihypertensive medicine used in Ghana, were analyzed with Energy Dispersive X-Ray Fluorescence spectroscopy (EDXRF). Analysis revealed 12 macro and 26 micro elements in both extracts. Further quantitative assessment of the results for amounts of elements that are pharmacologica...
