Practical elimination of near-duplicates from web video search

Abstract

Current web video search results rely exclusively on text keywords or user-supplied tags. A search on typical popular video often returns many duplicate and near-duplicate videos in the top results. This paper outlines ways to cluster and filter out the near-duplicate video using a hierarchical approach. Initial triage is performed using fast signatures derived from color histograms. Only when a video cannot be clearly classified as novel or near-duplicate using global signatures, we apply a more expensive local feature based near-duplicate detection which provides very accurate duplicate analysis through more costly computation. The results of 24 queries in a data set of 12,790 videos retrieved from Google, Yahoo! and YouTube show that this hierarchical approach can dramatically reduce redundant video displayed to the user in the top result set, at relatively small computational cost.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • None of the existing definitions addresses the retrieval of same incident videos.

    “However, there does not seem to be strong consensus among researchers about which videos are considered near-duplicate videos and none of the existing definitions addresses the retrieval of same incident videos ; in this paper, we attempt to address these issues and provide solid definitions for all types of associations between videos related to the FIVR problem.”

  • The labels in CC Web and UQ Video are only available on video-level, without timestamps of the copied segments.

    “the labels in the datasets are only available on video-level, indicating whether or not two videos are copies of each other without the timestamps of the copied segments”
  • Many copies in the CC Web and UQ Video datasets are easy to be detected as the transformations among them are very limited.

    “Many copies in the two datasets are easy to be detected as the transformations among them are very limited.”

  • CC WEB VIDEO has a relatively small volume and query set (12,790 videos and 24 queries) and lacks challenging distractors because its queries are very different from each other.

    “For instance, the volume and query set of CC WEB VIDEO are relatively small (12,790 videos and 24 queries), and the dataset lacks challenging distractors given that the queries are very different from each other.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
