1. based on the face recognition method of video, comprising:

  • Determine corresponding a plurality of similar frame of video in the video sequence in the video sequence that is identified and reference picture storehouse;

    The similar video frame of the correspondence in the video sequence in described video sequence that is identified and reference picture storehouse is carried out the aligning of reference point;

    From the described face data cube that is identified the video sequence through a plurality of frame of video formation persons of being identified behind the reference point aligning;

    WithDescribed face data cube is carried out subspace analysis, extracts the person'"'"'s of being identified facial characteristics, compare with facial characteristics vector in the described reference picture storehouse,Wherein, describedly facial data cube carried out subspace analysis comprise;

    From the feature sheet that cubical each frame of described face data is formed, extract and differentiate proper vector;

    In based on the sorter of frame, come each frame is discerned with described differentiation proper vector;

    AndUse fusion rule that the result of described sorter is merged, the video sequence that is identified is discerned.
