“…38 vectors for this experiment) are used in inverse KL transformation or inverse DCT, original global view can be obtained. If only first vector is used, the method is equivalent to our previous work [14] where the average along EPI represent the global view. However, in the case that less than 38 vectors are used in inverse KL transformation, original global view can not be obtained.…”

We propose a novel 3D space representation for multi-view video, using epipolar plane depth images (EPDI). Multi-view video plus depth (MVO) is used as common data format for FTV(Free-viewpoint TV), which enables synthesizing virtual view images. Due to the large amount of data and complexity of the multi-view video coding (MV C), compression of MVO is a challenging issue. We address this problem and propose a new representation that is constructed from MVO using ray space. MVO is converted into image and depth ray-spaces. The proposed representation is obtained by converting each of ray-spaces into a global depth map and a KL transformed global view using EPOI. Experiments demonstrate the analy sis of this representation, and its efficiency.
