  1. ANMRR(Average Normalized Modified Retrieval Rank) Defined in “Core Experiments onMPEG-7 Edge Histogram Descriptors,” ISO/IEC JTC1/SC29/WG11- MPEG/M5984, Geneva,Switzerland, May 2000 Reporter: Jen-Bang Feng Date: 2004/09/16

  2. Outline • Moving Picture Experts Group • MPEG-7 Standard • ANMRR • Example

  3. Moving Picture Experts Group • MPEG-1: A standard for storage and retrieval of moving pictures and associated audio on storage media • MPEG-2: A standard for digital television • MPEG-4: A standard for multimedia applications • MPEG-7: A content representation standard for information search

  4. Main Elements of the MPEG-7’s Standard • Description Tools: • Descriptors (D), Description Schemes (DS) • Description Definition Language (DDL) • System Tools • Core experiments content sets

  5. ANMRR (Average Normalized Modified Retrieval Rank) • The measure that exploits the rank of the retrieved images as well • lower ANMRR  more accurate retrieval • Between [0, 1]

  6. Example of ANMRR (Average Normalized Modified Retrieval Rank) A query qihas Ni = 10 similar images • Search for top 20 • found at 1, 5, 8, 13, 14, 18-th
