Abstract: | A novel method to extract a bounding box that contains the three-dimensional object from its spherical hologram is proposed.The proposed method uses the windowed Fourier transform to obtain the angular distribution of the quasi-collimated beams at each position in the spherical hologram and estimates the bounding box by accumulating the quasi-collimated beams in the volume inside the spherical hologram.The estimated bounding box is then used to realize occlusion effect between the objects in the synthesis of the three-dimensional scene hologram. |
