The demand for high-performance network video communications has been increasing exponentially in recent years. According to Cisco Visual Networking Index, "the sum of all forms of video (TV, VoD, Internet, and P2P) will continue to be approximately 90 percent of global consumer traffic by 2015". Whether the gap between consumer expectations and available video compression technologies can be filled in a timely manner would be a critical issue in the next 5-10 years for Canadian multimedia industry to survive the competition in the fast-evolving global market. An important aspect that has often been badly accounted for in current video compression systems is that human eyes are the ultimate receivers of the video content. Among existing objective perceptual image quality assessment methods, the structural similarity (SSIM) index achieves an excellent comprise between quality prediction accuracy and computational complexity.

近年来，对高性能网络视频通信的需求呈指数级增长。根据思科视觉网络指数，“到2015年，所有形式的视频（电视、VoD、互联网和P2P）的总和将继续占全球消费者流量的90%左右”。消费者的期望和可用的视频压缩技术之间的差距是否可以及时填补将是一个关键问题，在未来5-10年加拿大多媒体产业生存的竞争中快速发展的全球市场。在当前的视频压缩系统中经常被严重考虑的一个重要方面是人眼是视频内容的最终接收器。在现有的客观感知图像质量评价方法中，结构相似性（SSIM）指标在质量预测精度和计算复杂度之间取得了很好的平衡。
