Ghosting artifact resulted from angular undersampling is a major issue of light field rendering. In this paper, we propose an anti-aliasing method that compensates the effect of undersampling by making use of depth information. It can be incorporated into most existing refocusing algorithms to render high-quality images from light field. The method yields proper anti-aliasing across all depth range...
Various methods to determine loading of vaccine in biodegradable polymer microspheres encapsulating tetanus toxoid were evaluated. The microspheres were composed of poly(l-lactic acid) (PLA) and poly(dl-lactic-co-glycolic acid) (PLGA). Dissolution of microspheres in organic solvents such as methylene chloride, chloroform, or dimethyl sulfoxide and extraction of vaccine antigen or total protein with...
