Design and Application of Multi-Media Database System to the Study of Landscape Painting

我们研究了以下的多媒体数据库模型系统，用于分析风景画。(1)使用HyperCard的模型系统（2）使用SuperCard的模型系统（3）使用File Maker Professional和数据压缩板的模型系统（4）使用视频光盘播放器的模型系统（5）使用Hi-8视频播放器的模型系统（6）使用静止视频系统的模型系统（7）使用柯达照片CD系统的模型系统模型系统（1）和（2）是构建最经济的系统。但是，随着数据量的增加，它们的执行速度会变慢。这是图像数据库系统的一个关键缺陷。这种缺陷可以通过使用不同格式的图像数据和文本数据的分离来消除，图像数据通过数据压缩板处理，而文本数据在更可靠的数据库软件（比HyperCard或SuperCard）如File Maker Professional上建立参考系统。图像数据和文本数据的分离可以通过使用视频系统来实现。模型系统（4）比模型系统（5）更实用，因为前者采用随机访问，而后者是顺序访问。然而，这两种视频系统的静止图像质量都不令人满意，只有少数静止视频系统才能实现较高的视频图像质量。Model System（6）是使用经济型静止视频系统（Canon、Sony、Fuji Film等）的系统。在一两年内，使用照片CD系统（柯达）将获得更高质量的图像。图像数据库系统和参考系统之间的接口是各个研究领域，特别是视觉艺术研究和教育领域的迫切需要。

We examined the following model systems of multi-media database for analyses of landscape paintings.(1) Model System Using HyperCard(2) Model System Using SuperCard(3) Model System Using File Maker Professional and Data Compression Board(4) Model System Using Video Disc Player(5) Model System Using Hi-8 Video Player(6) Model System Using Still Video System(7) Model System Using Kodak Photo CD SystemModel Systems (1) and (2) are most economical systems to build. However, their execution speeds become slower, as the number of data increase. This is a crucial defect for an image database system. This defect can be removed through separation of image data and text data by using different formats, image data processed through a data compression board, while reference system built by text data on more solid database software (than HyperCard or SuperCard) such as File Maker Professional.The separation of image data and text data can be attained by using video systems. Model System (4) is more practical than Model System (5), because the former takes random access, while the latter is sequential. However, the quality of still image is not satisfactory in both video systems.Relatively high video image quality will be realized by a few still video systems. Model System (6) is a system using an economical Still Video System (Canon, Sony, Fuji Film, etc.). Images of much higher quality will be attained by using the Photo CD System (Kodak) in a year or two. Useful interfaces which connect image database system and reference systems is much needed in various fields of study, especially in research and education of visual arts.
