This paper address an algorithm of detection and tracking dim small multi-targets based on motion vector estimation.

Novel fast motion estimation algorithm based on optimizing predictive motion vector;

The conventional de-interlacing algorithms have some insurmountable faults, considering the characters of the true motion vector field based on motion estimation, a novel de-interlacing algorithm based on the measurement of motion vector is introduced, not consuming many hardware resources.

Conversion of frame types and motion vectors mapping in MPEG-2 to MPEG-4 real-time video transcoding;

The writer proposes a robust video watermarking scheme based on motion vectors.

Focusing on the problem of moving object detection and tracking on MPEG-4 compressed streams by a stationary camera,an algorithm for detecting the moving object using DC coefficients and motion vectors of the motion information in MPEG is presented.
