In this paper, we propose a novel snake algorithm for object segmentation that can be overcome the limitations found in cluttered background, overlapped object placements, and the problems of initial snake points. Our newly designed algorithm is developed by using disparity information taken from several sets of stereo images. The experiment results have(More)
The basic ideas for realistic and real-time animation of 3D character are described through three steps. First, we just choose two deformations among all kinds of deformations that happen in the human body, because these deformations are globally noticed and can be performed in real-time. Second, we decide what body parts of a character are deformed from(More)
Kenaf fibers have excellent properties and possess the potential to be outstanding reinforcing fillers in cement. The grafting of acrylamide to kenaf fibers is important in improving the compatibility between the fibers and the cement. Acrylamide was grafted onto kenaf fibers using gamma-ray radiation. The radiation dose ranged from 20 to 100 kGy, and the(More)
The aim of this study was to evaluate the ability of electron beam irradiation to drive stabilization reactions within PAN nanofiber mats to obtain carbon nanofiber mats. PAN nanofiber mats with fiber diameters of 300-400 nm were prepared via an electrospinning method. Electrospun PAN nanofiber mats were stabilized by electron beam irradiation with various(More)
Electron beam (e-beam) irradiation of polyacrylonitrile (PAN) was performed to investigate the effects of radiation on the electrospinning process. For this study, polyacrylonitrile powder was subjected to e-beam irradiation with different doses of up to 100 kGy under an N2 atmosphere. Polymer solutions were prepared by dissolving PAN in(More)
Composites of Fe93.5Si6.5 powder and epoxy (diglycidyl ether of bisphenol A type) were prepared using an electron beam irradiation process. Scanning electron microscope (SEM), vibrating sample magnetometer (VSM) and network analyzer were used to analyze the structure, electromagnetic properties and micro wave absorption of the composites. Results show that(More)
