- Abstract
- 텍스처 영상 압축은 JPEG과 같은 영상 압축 표준을 사용한다. 일반 텍스처 영상에는JPEG으로도 좋은 압축 성능을 내지만 패치 텍스처 영상은 이러한 영상 압축 기술로 압축했을 때 좋은 압축 성능을 보이지 못하였다. 이를 보완하고 압축 성능을 높이기 위해 기존의 패치 텍스처 영상에 주변 화소 간에 색차를 줄이기 위한 전처리 기술을 소개하고, 제안된 기술과 JPEG 압축을 순서대로 적용하였을 때 압축 성능이 23%에서 45%까지 향상됨을 보이고자 한다.
In mapping a texture image into a 3D mesh model for photo-realistic graphic applications, the compression of texture image is as important as geometry of 3D mesh. Typically, the size of the (compressed) texture image of 3D model is comparable to that of the (compressed) 3D mesh geometry. Most 3D model compression techniques are to compress the 3D mesh geometry, rather than to compress the texture image. Well-known image compression standards (i.e., JPEG) have been extensively used for texture image compression. However, such techniques are not so efficient when it comes to compress an image with texture patches, since the patches are little correlated. In this paper, we proposed a preprocessing method to substantially improve the compression efficiency of texture compression. From the experimental results, the proposed method was shown to be efficient in compression with a bit-saving from 23% to 45%.
