提出了一種基于樣本的分級檢索 MPEG 視頻的新方法:首先用I 幀的dct_dc_size 字段快速粗檢,然后用斷層攝影(tomography)法分析B 幀運動矢 量的時空分布特性以進一步縮小結果集,最后用DC 圖像的精確匹配方法驗證檢索結果.試驗結果表明,本方法 所需計算量較小,且可保證較高的檢索精度.

mp3設計程序資料，采用c語言編寫。 README file for yampp-3 source code 2001-05-27 This is the current state of the yampp-3 source code, 2001-05-27. This code is intended to run on Rev. B of the yampp-3 PCB, but can ofcourse be used on compatible systems as well. It still uses the "old" song selection system as the yampp-2. However, the disk handling routines has improved a lot and the obviosly, the new VS1001 handling has been put in. The codesize is almost at it s maximum at 1F40 bytes. A .ROM file is included if you don t have the compiler set up. For now, the documentation is in the code
