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)
BACKGROUND AND OBJECTIVES Stem cell-based therapy is a potential new approach in the treatment of stroke. However, the efficacy and safety of these treatments are not yet fully understood. Therefore, we performed a meta-analysis of available single-arm studies using stem cell-based therapy in patients with stroke. METHODS We searched MEDLINE, EMBASE, and(More)
Although blinding is a methodologic safeguard to ensure obtaining comparability of groups in a clinical trial, it is very difficult to maintain blinding from the beginning to the end of a study. The aim of the study was to see how proper blinding of both participants and treatment providers from the planning phase of the study to during the study affected(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)
Hypoxia in the tumor microenvironment is the leading factor in angiogenesis. Angiogenesis can be identified by dynamic contrast-enhanced breast MRI (DCE MRI). Here we investigate the relationship between perfusion parameters on DCE MRI and angiogenic and prognostic factors in patients with invasive ductal carcinoma (IDC). Perfusion parameters (Ktrans, kep(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)
