Fundamental Study on Construction of the Digital Museum Oriented Sensory Scalable Representation

把伟大的艺术作品和历史资料留给后人是非常重要的。需要对这些材料进行分类和存档，以防止老化变质。为了高保真地表现艺术作品，这些材料应该被数字化为超高清图像。此外，对于雕像或瓷器等固体材料，需要使用超高分辨率数码相机进行全方位拍摄。这些数字数据的量非常大，因此必须引入数据压缩技术。然而，诸如JPEG或MPEG的有损压缩方案对于这些图像数据的编码是不期望的。为了保持这些图像数据的高逼真度，必须引入无损压缩方案。从这一观点出发，我们在2001-2003年度的日本科学振兴会的科学研究资助（B）研究项目（批准号13450149）中提出了数字博物馆传输系统的基本概念。随后，我们研究了一个基于新思想的可伸缩传输的数字博物馆系统。即首先提出了数字博物馆的基本传输系统。该系统以运动补偿和马尔可夫模型为编码模型，以改进的自适应算术编码方法为熵编码器，研究了感知可分级传输系统的基本概念。此外，我们考虑了通过网络传输的各种问题。特别地，我们提出了新的数字水印系统的版权保护和防篡改。

It is very important to leave great art works and historical materials on the future generations. It is needed to digitize and archive these materials to prevent an aged deterioration. In order to represent art works with high fidelity, these materials should be digitized as super high definition images. Moreover, for solid materials like statue or china it is needed to take photographs by super high resolution digital camera in all directions. Amounts of these digital data are very large, so that data compression techniques have to be introduced. However, the lossy compression schemes such as JPEG or MPEG are not desirable for coding of these image data. In order to preserve these image data with high fidelity, loss-less compression schemes should be introduced.In this point of view, we already proposed the basic concept of the transmission system for the digital museum in the research project Grant-in-Aid for Scientific Research (B) of the Japan Society for the Promotion of Science (Grant No. 13450149), in 2001-2003. Successively, we have been studying a system of the digital museum using a scalable transmission based on new idea. Namely, at first, we proposed the fundamental transmission system of the digital museum. In our system, the motion compensation and Markov model are used as the coding model, and the modified adaptive arithmetic coding method is used as the entropy coder and secondary, we studied the basic concept of a sensory scalable transmission system. Moreover, we considered the various problems in the transmission via the network. Especially, we proposed the new digital watermarking system for copyright protection and tampering prevention.
