In a high school education, a new subject of computer design aims at the acquisition of the fundamental knowledge of a design or operating skill of computer in the field of visual communication. We consider that it is necessary to adopt basic design education to the lesson of this subject which acquire both skills of computer and design in order to raise the composing ability needed for creation of a high-quality design, esthetic judgment, and power of expression. However, evaluating a work of a basic design subject is a hard task for the teacher except for a specialist of design. Thus, we propose an evaluation support equipment for the basic design education. In this paper, a color composition subject is taken up, and it is discussed how to support the evaluation by the equipment based on image processing. We also discuss the performance and the feeling of the usage of this equipment.
As for the present people, the real expression of CG in the amusement can't get strong impression. Visualization was proposed to the fresh expression of CG there by this research. It was made to visualize a transparent object by more than one particle. The matter whether the visualization image of different particle gave the people what kind of sensitivity was investigated. The questionnaire of the visualization image was done, and it got data. A factor analysis was done in the data, and a difference in the sensitivity was explained.
There are some studies that high-resolution images generate more α-waves in our brains. In this paper, we discuss the reason why these studies are not always true. After that, we propose a new hypothesis, in which there is a strong relationship between recognition distance and resolution and we proved that our hypothesis is true.
The rapid expansion of personal digital multimedia content in recent years requires a systematic indexing, categorizing and browsing interface to manage these enormous data. To tackle this crucial problem, the MPEG-7 standard was initiated with the intention to allow for efficient searching, indexing, filtering and accessing of multimedia content. We propose a MPEG-7 based multimedia content description tool which annotates multimedia data with twelve main attributes regarding its semantic representation. The twelve attributes include answers of who, what, when, where, why and how (5W1H) the digital content was produced as well as the respective direction, distance and duration (3D) information. We define digital multimedia contents including image, video and music embedded with the proposed semantic attributes as Dozen Dimensional Digital Content (DDDC). The establishment of DDDC would provide an interoperatable methodology for multimedia content management applications at semantic level. We also envision novel algorithms associate with DDDC attributes for semantic based content retrieval in the future.
This paper describes a knowledge-based approach to set up a scene, determining the corresponding shot types and shot sequence. Screen layout and virtual camerawork dependent on the cinematic expertise stored in a domain knowledge base. We model the filmmaking knowledge and rule-based reasoning strategies in expert system language CLIPS.
We propose a new feature description method of video using statistics processing for motion vector. A new method has advantages of fast retrieval time for pick up any desired specific scenes. As the picture of the retrieval object, baseball scenes were studied and optimal parameters were clarified to extract the pitching scenes.
In the VOD services, low resolution video data is suitable for contents searching, on the other hand, hi resolution video data is expected for browsing. Even if the client has already received low resolution video data as search results, the traditional simalcast method have to send whole hi resolution data which includes same information with low resolution data. To decrease the traffic between VOD server and the clients, we propose an application of scalable coding to cache server which is located in the site of VOD clients. By the application of scalable coding, the traffic between VOD server and the site of client is remarkably decreased.
Biometrics authentication techniques are in the stage where we are required more reliable techniques, as an alleviation of the vulnerability. In this paper, we considered the individual authentication using biometrics from aspect of "KATACHI(form)". We note the importance of the hidden characteristics which "KATACHI(form)" has and verified an alleviation of the vulnerability.
It has been understood that the method of making the Gaussian-Laplacian filter of s=0.625 from s=1 act on the signal which reproduces only from high frequency elements at level 2 or more obtained by wavelet multiple decomposition is effective.
There are many kinds of wood board used in Japanese house, for construction, floor or panels. In these boards (timber), there are many kinds of grade for their uses. It's better to be few knots on the surface of board, especially used in cell, floor or wall. They are estimated by the number of knots and by beauty of its wood grain. We have developed automatic estimation system to measure the quality of timber.
In this paper, we propose a method for generating images when a light source moves, based on interpola- tion methods. Combining two interpolation methods, i.e., isophotal curve interpolation and image interpo- lation, a realistic image due to in-between light source position can be generated quickly. The usufulness of the poposed method is demonstrated by rendering an indoor scene under interreflective environment.
