본 논문에서는 로봇이나 감시 시스템에서 주로 쓰이고 있는 배경 모델링의 정확성을 지속 시키는 방법을 제안한다. 오브젝트를 추출하려면 정확한 배경 모델이 필요하다. 정확한 배경 모델을 유지하기 위해서는 전경의 정보가 배경 모델에 반영되면 안 된다. 본 논문에서는 오브젝트의 움직임을 기반으로 한 배경 무효화 기법을 사용 하여 전경이 배경 모델에 영향을 주는 것을 방지함으로써 정확한 배경 모델을 유지하는 방법을 제안한다.

This study investigated the durability of the concrete to improve construction materials with polymer cement mortar. With the popularity of repair and rehabilitation material, some mixtures composed of Styrene-Butadiene Rubber (SBR) and Ethylen Vinyl Acetate (EVA) were studied. The two composite carried out the chemical resistance test. The results on the appears that the application of polymer cement is very beneficial in improving chemical resistance, specially EVA, which has been found to have a significant resistance to sulfate solution. This resistance is due to the filing and sealing effects of the impermeable polymer films formed. In conclusion, the addition of polymer to the cementitous materials improved the concrete properties and supplemented the defects in an efficient manner. Furthermore, it can be used as a repair and rehabilitation materials for reinforced concrete structures and as a resistance material in marine environment.
