3차원 영상의 블록 중복성 및 N-LUT 기법을 이용한 3차원 홀로그램 프린지 패턴의 고속합성 = Fast Generation of 3-D Hologram Fringe Patterns by using the Block Redundancy of 3-D Object Images and the Novel Look-up Table Method

다국어 초록 (Multilingual Abstract)

Recently, the novel loop-up table(N-LUT) method to solve the tremendous memory problem of the conventional look-up table (LUT) method as well as to increase the generation speed of hologram patterns has been proposed. But, as the resolution of an input 3-D object is enhanced, the number of object points to be calculated for generation of its hologram pattern also increases, which results in a sharp increase of the computation time. Therefore, in this paper, a new approach for fast generation of the hologram pattern of 3-D object images is proposed by using the block redundancy feature of 3-D object images and the N-LUT method. Experimental results show that in the proposed method the number of object points and the overall computation time have been reduced by 43.3 % and 47.9 %, respectively compared to those of the conventional method for the case of the $5{\times}5$ block size. These good experimental results finally confirm the feasibility of the proposed method.
