This paper presents a method to detect moving objects and remove their shadows for superimposing them on Mixed Reality (MR) systems. We cut out the foreground from a real image using a probability-based segmentation method. Using color, spatial, and temporal priors, we can improve the accuracy of the segmentation. Energy minimization is executed by graph cuts. Then we remove the shadow region from the foreground with F-value calculated from the pixel value and the spectral sensitivity characteristic of the camera. Finally we superimpose virtual objects using the stencil buffer, which is used to limit the area of rendering for each pixel. Synthesized images of an outdoor scene show the efficiency of the proposed method.
