多光谱成像在某种程度上在卫星图像获取中很常见，最近正用于视觉成像系统，如打印机、数字/模拟相机、静态/视频相机、投影仪甚至显示器。原因是它提供的各种功能。由于图像数据的量与频带的数量成比例，因此需要对这样的数据集（特别是对于视频数据）进行有效压缩。本文对多光谱视频编码的基本问题进行了研究，如带间去相关、可见/不可见分离和编码前的非线性信号变换等。我们使用一个六波段的视频序列（48 bit/pel）作为测试数据。介绍了Motion JPEG 2000、MPEG-4 Studio Profile等视频/图像编解码器以及新开发的H. 264/AVC，在编码实验中进行了比较。
Multispectral imaging, which has been common in satellite image acquisition to a certain extent, is recently being used in visual imaging systems such as printers, digital/analog cameras, still/video cameras, projectors and even displays. The reason is the variety of functionalities it provides. As the amount of image data is proportional to the number of bands, efficient compression of such data sets, particularly for video data, is necessary. This paper provides a basic investigation of multispectral video coding, such as inter-band decorrelation, visible/invisible separation and non-linear signal transform prior to encoding. We use a six-band video sequence (48bit/pel) as the test data. The video/image codecs of Motion JPEG 2000, MPEG-4 Studio Profile, as well as the newly developed standard H. 264/AVC, are compared in a coding experiment.
