Video copy detection - Benchmark

Sample of Video Comparer result of Youtube Benchmark

The benchmarking process

Two benchmarks have been done, one from YouTube, another from MUSCLE-VCD-2007 challenge.

Benchmarks compare the result of different softwares (Duplicate Video Search, Teemoon Video Matching, Video Comparer) and publications.

The measures:

  • The percent of positive duplicates found
  • The speed of the analysis (the total duration of videos divided by the analysis duration)

Computer specifications

Processor : Intel Core i7-2600K @ 3.40GHz
Memory : 8GB
Hard drive : 2TB 7200rpm Raid0
Operating system : 64-bit Windows 8

 

YouTube Benchmark

The videos used for this benchmark have been downloaded from YouTube. This database contains 98 video clips of a total length equal to about 55 hours. The content of these videos are very various (cartoons, old movies, short movie trailers, sports).

Softwares parameters:

  • Teemoon Video Matching (1.0.5): Default.
  • Duplicate Video Search (16.0.0): Video indexing to 100s, Skip first to 180s, Max shift to 30s.
  • Video Comparer (1.04.004): Thorough scan mode.

VCD2007 ST1 Benchmark

The video database used for this benchmark is MUSCLE-VCD-2007. This database is very interesting for performance comparison, because many teams have developed algorithms and published their results.

The process involves two phases:

  1. The large database DB-MPEG1 is learned. This database contains 101 video clips of a total length equal to about 80 hours. These video clips come from several different sources such as the web video clips, TV programs and movies. They cover a wide range of categories, including movies, commercials, sports games, cartoons, etc.
  2. The query database ST1Queries is processed. There are 15 query video clips with a total length a little more than 3 hours. Ten query video clips are attacked by one or more changes, or transformations while the remaining five video clips were not from the database. The transformations includes re-encoded, noised, or slightly re-edited.
