In this thesis, we describe the necessary capabilities for database management systems and compare them with the limitation of RDB. And also we introduce object database and its efficiency, which will be the new trend of the database. We use “Jasmine2000” as a concrete example of object database in business use, and are going to verify its efficiency with its applied cases. At the end, we will point the way of database's future.展开更多

Using the proposed method, we can obtain a digital still camera image and spectral information in different environments. Also, it is not necessary to estimate reflectance spectra using a spectral database such as other methods. The synthesized images are accurate and high resolution. The proposed method effectively works in making digital archive contents. Some experimental results are demonstrated in this paper.展开更多
