초록
JPEG(Joint Photographic Experts Group) 표준안은 디지털 정지 압축을 위하여 국제표준화기구(ISO/SC29/WG10)와 국제전신전화 자문회의(CCITT SG VIII)에 의해서 제안되었다. JPEG 표준안은 전자영상, 컴퓨터 그래픽, 멀티미디어 등과 관련하여 널리 응용되고 있으나, 의료 영상분야에서는 JPEG 압축의 손실 특성 때문에 사용이 매우 제한적이었다. 본 논문에서는 JPEG 표준안을 핵자기 공명 단층 영상 (256 gray levels,
The Joint Photographic Experts Group (JPEG) standard was proposed by the International Standardization Organization (ISO/SC 29/WG 10) and the CCITT SG VIII as an international standard for digital continuous-tone still image compression. The JPEG standard has been widely accepted in electronic imaging, computer graphics, and multi-media applications, however, due to the lossy character of the JPEG compression its application in the field of medical imaging has been limited. In this paper, the JPEG standard was applied to a series of head sections of magnetic resonance (MR) images (256 gray levels,
