Shadow removal in front projection system using skeleton model

Abstract

Front projection system is used in various fields to emerge interative system. When the user is located between a screen and a projector in these system, a shadow is cast on the screen. The shadow on a screen negatively affects the user experience in an interactive system. This shadow can also eliminate important information. There has been various researches to remove shadows on a screen by using overlapped projectors. We propose a novel approach method to remove shadows in front projection system using skeleton data. Due to shadow region estimation using skeleton data, a proposed method can deduce the region following shape of shadow that the user cast. Our method also propose distance field to remove the afterimage of shadow that occur when the user moves. We will show that our system performs shadow removal in interactive environment consist of front projection system.
