Video Copy Detection

Early Idea

• Collect large set of videos (may be from TREC)

• Extract local features (e.g., SIFT) from I frames

• Cluster these features into K clusters using for example K-means method (need to try for different values of K)

• To create signatures

• • Divide a video into groups (may be GOP)
  • Extract local features from I frames
  • Map these features to the K clusters (prob value for each cluster)

• Extract motion vectors from
