    We previously proposed the System of ACTIT, Automatic Construction of Ttree-structural Image Transformations. In this study, as a method to improve the ACTIT System, we installed modifying weighted images that extended weighted-images implemented before. Modifying weighted-images made by a user or the system itself during optimization of tree structural image transformations worked effectively to approximate user's aimed image processing.

    In this paper, a new encoding method of stereo pictures using wavelet transform is proposed. In today's researches, encoding method of stereo pictures using Discrete Cosine Transform(DCT)and parallax compensation has been investigated. But encoding method using DCT bring on the block noise. To overcome the difficulty, we will discuss to use wavelet transform instead of DCT in the proposed encoding system. Then we use parallax compensation by overlap block matching when we search for parallax vector. Subjective evaluations on computer simulation show that the proposed method is better than conventional method. This encoding method has been effectively verified by the simulation results.

    In the conventional Video On Demand(VOD)system for medical service, two or more streams are generated and stored from one video source for every resolution(HDTV, SDTV, SIF, etc.)to need. For this reason, storing efficiency is bad in such system. First, we decided to avoid duplication of video data by using an MPEG-2 spatial scalable coding system in this research. Furthermore, when storing the generated stream to a server. We stored separately these streams for every resolution in these servers. By this composition, it is enabled to improve the storing efficiency and to distributed the load of a server system.

    An image retrieval system using Image Compression method based on Fuzzy relational equation(ICF)is proposed. In this system, after a color image is compressed by ICF, the average and standard deviation of pixels as well as higher order local autocorrelation of the whole image are calculated and indexed. In this way, the proposed method results in 13 〜 25% decrease of computation time(with compression rate 0.0156 〜 0.0625)compared to the same sequence of operations executed on the non-compressed image. The result of the image retrieval experiment using 30 images confirmed the better performance(precision and recall)of the proposed system over that of a non-compression method.

    This paper presents a methodology for handling soccer game scenes on a database. We offer a new modeling method, along with relevant database design and storage technique for the media analysis data. When modeling complex, spatio-temporal information as the one involved in soccer game scenes, information standardization vs.representation of individual information is a very important issue. As a solution, in this research the Cartesian aggregation of standard and individual element is regarded as an entity, and is modeled through the Mediator concept. Also, we show that such an approach makes possible the representation of information about Mediator's location in the media. Further, employing the model, soccer game scenes information is broken down into time-independent and time-dependent parts, and each is stored in the database with a relevant schema.

    With the spread of input devices such as scanners and digital cameras, hundreds of thousands of digital images are now being created and distributed. It will be necessary to find a way to manage and retrieve desired images easily from such a large amount of low-cost image data. This paper presents easy and high performance retrieving and overlooking functions for finding desired images base on image features. Also, by adopting the same idea to another media, the retrieval functions for video, 3D, music are presented.

    The Yokohama Broadcast Library was opened in the Yokohama Media and Communications Center in October 2000. In the Library, people can watch a range of programs that have already been broadcast, using TAO's experimental viewing system. All programs are digitized and distributed to viewing booths from a video server and DVD cart machine. Remote viewing booths have been set up in Osaka, allowing people in Osaka to watch programs that are in Yokohama through TAO's gigabit network in realtime. This paper reports on the specifications, configuration and operation of the system.

    The information system in the Yokohama Broadcast Library which opened in October 2000 consists of a data input terminal, data searcher, information desk, and database server which manages the database of TV and radio programs. When a TV or radio program is selected using the data sercher, the information desk issues the viewer's instructions to the viewer system. This paper outlines the configuration and operation of this information system.

    Many of color-based image retrieval methods use a single color histgram extracted from a whole image for similarity evaluation. However, these methods cannot represent spatial color information within the image. In this paper, to overcome the problem, we use multiple histgrams extracted from regions obtained by a segmentation of the image, and the relationship between the region and its adjacent regions for similarity evaluation between the images. Moreover, having an index for every region, our method can retrieve a part of the image. We show some results of image retrieval experiments by comparing our method with conventional one.

    We propose a new feature for content-based image retrieval using sketch. The proposed feature is based on the shape of object's edge. The feature extraction method uses the relative positional relationship between pixels on binary lines image as histogram. Hence this feature has advantage of rotation-invariant, shift-invariant and scale-invariant. Applying the proposed feature to image retrieval, it is possible for users to retrieve objective images by rough sketch drawn with input devices(mouse, electronic pen, etc.). To verify the effectiveness of this method, we tested the method on two separate databases. Experimental results show that the proposed method is effective.
