적응적 3D-DCT를 이용한 집적영상 압축 방법

In this paper, we propose an efficient compression method of the integral images. The integral imaging is a well-known technique to represent and record three-dimensional images. The proposed method is a compression method efficient to integral images using 3D-DCT technique. The 3D-DCT blocks adaptive to the characteristics of integral images are constructed and then 3D-DCTs for the 3D blocks are performed. Experimental results show that the proposed method can give bit-rate reduction of about 10% .
