Edge-based active contour models usually use an edge detector function depending on the image gradient to stop the evolving curve on the object boundary (Caselles et al. 1993; Kass et al. 1988; Malladi et al. 1993). These models have few weaknesses like sensitivity to noise, initialization ...
According to the C-V characteristic between PECVD SiO2 and p-type 4H-SiC, the the interface state density between is calculated to be 4.87×1011 cm−2 eV−1 (0.1 eV from the valance band edge), indicating that the slight current gain drop is attributed to the improvement of ...
