Abstract:
Disclosed is a technology related to a method and an apparatus for searching hologram by recovering an image based on hologram redundancy. The method for searching hologram includes the steps of filtering hologram data based on the hologram redundancy; back-tracking depth information of an image based on the filtered hologram data to analyze the filtered hologram data; creating a recovery image based on the depth information of the image; and searching, ranking, and comparing images similar to the recovery image based on the image similarity. Accordingly, a distinguishable recovery image is created by using only some of the hologram data based on the hologram redundancy, and the similar images can be effectively searched based on the recovery image.

PURPOSE: A projection-based digital hologram display system and a method thereof are provided to visualize digital hologram data as a hologram image on a three-dimensional hologram display screen with a projection method through space buoyancy, thereby displaying the three-dimensional hologram image at the same level as the existing image display. CONSTITUTION: A hologram synthesis part (103) receives hologram data of a fringe pattern (104) and generates a hologram array by combining the fringe pattern, a background image, and a foreground image. A hologram projection part (101) supplies a light source (105) to the generated hologram array and projects a hologram image through a wide-angle lens (106). A hologram display part displays the projected hologram image on a three-dimensional hologram display screen through space buoyancy.

Abstract:
A hologram data processing method using a hologram fringe data format adaptive to a data encoding scheme comprises the steps of: configuring model data of a three-dimensional object corresponding to source data to be used for generating a hologram; computing hologram fringe data by applying a diffraction transform to a light wave transferred to a hologram plane based on the model data of the three-dimensional object; setting, in the computed hologram fringe data, the hologram fringe data format adaptive to a data encoding scheme for reconstructing the hologram; reconstructing an optical hologram by applying the data encoding scheme to the hologram fringe data; and adjusting the optical hologram by comparing a reconstructed image of the optical hologram to a reconstructed image of a numerical hologram.
Abstract:
PURPOSE: A stereoscopic image display device without glasses and a method thereof are provided to prevent a distortion phenomenon of a stereoscopic image which is generated by a layout structure of a display while maintaining a projection method of display. CONSTITUTION: A stereoscopic image display device without glasses(10) includes a stereoscopic image display(101) and a reflection structure. The reflection structure includes a total reflection mirror(104) and a half-reflection mirror(105). The total reflection mirror completely reflects the light of a stereoscopic display screen and changes the direction of light. The half reflection mirror transmits half of the light which is reflected from the total reflection mirror and reflects the other half of the light. A stereoscopic image is reflected through the total reflection mirror and the half reflection mirror, is formed on a projection surface(106) of a virtual image surface, and reaches the eyes of a user(107).
Abstract:
PURPOSE: A gradual vocabulary tree structure building method for image data search is provided to ease implementation by applying a depth map including brightness information to a vocabulary tree structure. CONSTITUTION: Local feature information is extracted by inputting a depth map of an object unit and a gradual vocabulary tree is composed by using the local feature information(S100). An excellent node is selected by using feature information of a leaf node of the gradual vocabulary tree(S200). The gradual vocabulary tree is updated by inserting the local feature information into the leaf node(S300). If the gradual vocabulary tree is updated, the excellent node is reselected in a previous step(S400). [Reference numerals] (AA) Start; (S100) Extract feature information of an image and build an initial gradual vocabulary tree; (S200) Select superior nodes of the gradual vocabulary tree; (S300) Extract feature information and search a corresponding leaf node when a new image is inserted; (S400) Update the gradual vocabulary tree
