摘要:
A method and apparatus for fast generation of a hologram image. The method may include generating a point hologram corresponding to each three-dimensional (3D) point using sub-sampling, generating a hologram pattern using the generated point hologram, and generating a 3D hologram by interpolating the generated hologram pattern.

A method and apparatus for fast generation of a hologram image. The method may include generating an elemental fringe pattern of a three-dimensional (3D) point included in a 3D spatial object, generating a point hologram based on the elemental fringe pattern, and generate a 3D hologram using a hologram pattern for each depth layer, generated using the point hologram.

摘要:
Provided is method and apparatus of compressing and restoring an image using filter information. The image compression apparatus may generate a reduced image by sampling an input image, determine filter information based on the input image and a decoded reduced image, and code the filter information and the decoded reduced image. Accordingly, a deterioration in an image quality may be prevented in transmitting the image using a limited bandwidth.
摘要:
A multi-view image coding apparatus and method are provided. The multi-view image coding apparatus may extract geometric information from a plurality of cameras, may construct a spatial prediction structure to enable a correlation of each view to be maximum using the geometric information, and thereby may code and transmit a multi-view image.
摘要:
A method and apparatus for encoding an image, and a method and apparatus for decoding an image are provided. In the image encoding method, an input image may be encoded hierarchically based on a unified image compression format, irrespective of whether the input image corresponds to a two-dimensional (2D) image, a stereo image, or a three-dimensional (3D) image. An encoded bit stream generated through the encoding may be transmitted to the image decoding apparatus.
摘要:
Provided is an image processing apparatus. In the case of a multi-view image, the image processing apparatus may warp a color image and/or a depth image of a reference view to correspond to a target view. An occlusion region may be extracted by comparing the warped color image and/or depth image of the reference view with a color image and/or a depth image of the target view. The image processing apparatus may encode the extracted occlusion region information without loss, and decrease an amount of data in the multi-view image.

Disclosed is a 3D video motion estimating apparatus and method. The 3D video motion estimating apparatus may enable a motion vector of a color image and a motion vector of a depth image refer to each other, thereby increasing a compression rate.
