ABSTRACT
In the design of multimedia database systems, one of the important issues is how to
deal with “impression” of human beings. The concept of “human impression” includes
several meanings on sensitive recognition, such as “human senses,” “feelings,”
“sensitivity,” “psychological reaction” and “physiological reaction”.
In the field of database systems, the concept of multimedia databases is related to
data definition and data retrieval with information on human impression for multi-
media data, such as images, music and video. The important subject is to retrieve
images and music dynamically according to the human impression. In this chapter,
we describe some multimedia systems which manipulate information on human im-
pression for defining and retrieving multimedia data.
In the research field of multimedia database systems, it is becoming important to
deal with information on human impression for defining and retrieving media data
according to impressions and senses of individual users.
The conceptual overview of a multimedia database system dealing with informa-
tion on human impression is shown in this chapter. The essential functions for deal-
ing with human impression are summerized. There are several research projects to
realize these functions. In the design of the information on human impression for
media data, the important issues are how to define and represent the metadata of
media data and how to extract media data dynamically according to the user's im-
pression and the data contents. Creation and manipulation methods of metadata for
media data are summerized. Furthermore, some research projects for information on
human impression are introduced.
