Abstract:
Provided are an apparatus and a method to compress an image through a frame prediction. By analyzing a video signal, a similarity rate between a frame at a coding time and a previous input frame is compared with a reference similarity rate, respectively. When the similarity rate between the frame at the coding time and the previous input frame is equal to or greater than the reference similarity rate, the frame at the coding time is compressed using a frame vector including an identification information about a reference frame similar to the frame at the coding time. When the similarity rate between the frame at the coding time and the previous input frame is less than the reference similarity rate, the frame at the coding time is compressed through an intra or inter coding scheme.

Abstract:
Disclosed is an apparatus for identifying the authenticity of a holographic image which can identify the authenticity by comparing a holographic image displayed by emitting light with an identical characteristic to an emitting characteristic of a first reference wave used when the holographic image was created with an original image. As a result, when a hologram is made, an image or a pattern is recorded by using a reference wave at a particular angle and on a particular laser waveband. Therefore, the hologram cannot be easily duplicated or copied to forge.

The present invention provides a method and apparatus for correcting the distortion of an optical lens of a DHP system. The method includes the steps of: obtaining a distortion image; generating a distortion function of the lens from the obtained distortion image; generating an inverse function of the distortion function of the lens from the distortion function of the lens; and correcting the distortion of the lens by using the inverse function of the distortion function of the lens. The present invention forms the DHP system capable of recording a holographic image with reality by reducing a distortion phenomenon due to the optical lens.

The present invention relates to a method and an apparatus for inducing motion information by using a depth information value. The present invention includes a method of allowing several blocks to share and use a specific depth information value to decrease a memory bandwidth due to approach of the depth information value when motion information is induced by using the depth information value. Thus, the present invention can reduce the memory bandwidth of coding and decoding in a video coding process.

Abstract:
PURPOSE: An intra prediction mode decoding method and an apparatus for the same are provided to use an integrated signaling method in order to apply some of various intra prediction methods to an image selectively or altogether. CONSTITUTION: A decoding apparatus parses intra prediction mode information about a current block in a depth information map image (S1010). The decoding apparatus determines an intra prediction mode about the current block based on the intra prediction mode information (S1020). The decoding apparatus draws a final intra prediction mode about the current block by renewing the intra prediction mode according to a predetermined condition (S1030). The intra prediction mode information includes at least one of remaining intra prediction mode information and most probable mode (MPM) information.
