    摘要： The present invention relates to a system and method for displaying and capturing holographic true 3D images. The system comprises elements which may form both a wide viewing angle holographic true 3D display and a holographic true 3D video camera. The system mainly comprises a light source, a spatial light modulator or an electro-optical capturing device in different embodiments of the invention, a phase plate, a computer and an opaque mask in some embodiments of the invention.

    摘要： A rule-based method which detects and tracks the moving objects in video frames in an automated way is invented. The method can be used in object based image sequence compression applications. Motion of pixels between two consecutive frames are estimated using a block based motion estimation method, and the resultant dense motion vector field is segmented. Using the same method, a second segmentation is achieved based on partitioning of the image according to color values of the pixels. The image, which is formed by the translation of the final segmentation results of the previous frame using the estimated motion vectors, is used as the third segmentation. By the help of a sequence of rules, which uses the three different segmentation masks as its inputs, detection and tracking of moving objects in the scene is achieved within accurate boundaries; the problems caused by occlusion or uncovered background are insignificant.

    摘要： A holographic display and more particularly an apparatus and method for a curved electro-holographic display are disclosed. The apparatus mainly includes at least one light source for providing lights, at least one axially symmetric mirror for reflecting the lights coming from the light source, at least one spatial light modulation system having one or more than one spatial light modulators for modulating the lights reflecting from the axially symmetric mirror and forming a desired optical reconstruction above the axially symmetric mirror by reflecting the lights which is seen from a viewing zone by the user.
