Video retrieval of mpeg compressed sequences using dc and motion signatures
N Dimitrova, MS Abdel-Mottaleb - US Patent 5,870,754, 1999 - Google Patents
Signatures from MPEG or Motion JPEG encoded video clips are extracted based on the
luminance, chrominance, and motion vector values. The signatures are stored in a
database, along With corresponding location, siZe, and time length information. The
signature of a query video clip, also encoded in the MPEG or Motion JPEG format, is
extracted. The signature of the query video clip is compared With the signatures stored in the
meta database, With video clips having signatures similar to the signature of the query video …
