This work describes a novel Interpolation algorithm for ray-space reconstruction constrained with image segmentation. Arbitrary view generation is key technology for 3D-TV applications, where the user can take any position and viewing direction in a 3D environment. With the assumption that disparity varies smoothly over a color segment, we use an adaptive window-based matching method that is robust to outliers and gives better disparity estimation. Our segmentation of the original views is done using the Mean-Shift algorithm. Initially, we derive trusted pixels through a cross-check matching step. The trusted pixels are then used to define a disparity plane for each segment, which makes it possible to correct the disparity values of outliers. Novel views are then generated using the obtained disparity map and the captured images. The experimental results verified the robustness of our approach.
