Abstract :
The discrete wavelet transform (DWT) can provide multiple resolution and global decomposition. This advantage can be used to carry out the video processing applications both in software and hardware broadly. The ADV611 is one dedicated chip using DWT to implement video compression especially in video surveillance systems. In this paper we present a scheme using the technique similar to the MPEG4´s sprite to reduce the output bit rate and achieve high rate compression at acceptable quality. The experiment result using sprite to preprocessing input video stream and without any preprocessing are compared, the higher performance is showed.
