In video surveillance system, it is very necessary
and important to find out high efficient video retrieval
techniques and advanced video compression
techniques. Combining video retrieval technique with
video compression technique, this paper presents an
improved video compression algorithm. Our
experimental results show that the algorithm presented
in this paper not only increases the compression ratio,
but also improves the quality of the video reverting
from compressed video and improves the efficiency
and performance of the later video retrieval.
