Comparing interlaced and progressive scans for MPEG coding of medical video

摘要

This paper examines MPEG-4 coding efficiency for interlaced and progressively scanned video data recorded during remote patient monitoring. Experiments are performed using both interlaced and progressive coding methods to compress interlaced, deinterlaced and progressively scanned video sequences at different bit rates. Our results show that progressively scanned video outperforms interlaced video in both coding efficiency and video quality. We also found that the use of a deinterlacing algorithm improves video coding performance. In addition, we found that interlaced or progressively scanned video data can be compressed using either progressive or interlaced coding algorithms without significant difference in performance.
