IEEE Region 10 International Conference TENCON
作者: Satoshi Sakamoto Tadahiko Kimoto Graduate School of Engineering Toyo University Kawagoe Saitama Japan Faculty of Engineering Toyo University Kawagoe Saitama Japan
In the adaptive intra refresh method adopted in MPEG-4, a case that errors occurring in transmission propagate frame to frame and also spread inside a frame is still observed. This paper proposes a modified method for... 详细信息

IEEE International Conference on Image Processing
作者: Marta Mrak Nikola Sprljan Ebroul Izquierdo Multimedia and Vision Research Group Queen''s Mary University of London London UK
Motion information scalability is important for scalable bit-stream adaptation on low bit-rates, when motion rate occupies a significant portion of the total bit-rate. This type of scalability can be achieved by layer... 详细信息

COMMENTS ON COMPRESSION OF THE ECG BY PREDICTION OR INTERPOLATION AND ENTROPY ENcoding - REPLY
收藏 引用
IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING 1980年 第11期27卷 674-675页
作者: RUTTIMANN, UE PIPBERGER, HV GEORGE WASHINGTON UNIV MED CTRDEPT CLIN ENGNWASHINGTONDC 20037 GEORGE WASHINGTON UNIV MED CTRDEPT MEDWASHINGTONDC 20037
A recent paper1 discusses prediction and interpolation for data compression of ECG. This communication points out that both methods can be viewed as linear filtering. They are therefore equivalent and give the same re... 详细信息
