Abstract :
This paper provides a basic investigation of multispectral video coding techniques, such as interband decorrelation, visible/invisible separation, and nonlinear signal transform prior to encoding. A six-band video sequence (48 bit/pel) is used as the test data. The video/image codecs of JPEG 2000, MPEG-4 studio profile, as well as the newly developed standard H.264/AVC, are compared in a coding experiment. Investigation of the optimal encoding parameters, optimal bit allocation among components, subjective evaluation of decoded images, and optimal spatial resolution of each image band are some of the future works.
