SYSTEM AND METHOD FOR ADAPTIVELY ENCODING SEQUENCE OF IMAGE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an adaptive field/frame encoding method including effective rate control taking motion activity into account. <P>SOLUTION: Each image is a video signal consisting of two fields. Each image is first separated into a top-field and a bottom-field. Motion activity is extracted from the top-field and the bottom-field, and each image is encoded using either frame encoding or field encoding depending on the extracted motion activity. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
