This paper presents a design of special hardware developed for enhancing the floating-point power operations which are actively used at the lighting stage to calculate the specular term in 3D graphics geometry engines. The power operation takes just 4 cycles in our floating-point multiplier while it takes about 100-200 cycles in conventional floating-point units. Although an approximation algorithm is employed in the power operation to reduce the hardware complexity required, the error of power value from the developed floatingpoint multiplier is so minimal that no difference can be found by human eyes.

This Study is to divide aspects broadly that can be suggested with eyes to contemporary issues through assertions of contemporary theorists. verify those on case studies. and search for criteria on the framework of composition on expression of contemporary architecture. As the proposal of this study. the unified approach through a deductive and inductive study in the light of humanism and design creativity can establish the built environment considering human-centered architecture.

Light flicker is a notorious phenomenon influencing light quality. The flicker of the light flux outputs from the light sources perceived by human eyes depends upon the lamp brightness fluctuations for projector display. This paper describes a ballast ignition control system, which makes the lamp strike frequency phase lock the blanking time period to minimize the flicker effect

It is need to find a new feature for the more statable recognition system. Now, we need more features like a human eyes. Therefore, this paper proposed a new feature with the stereo camera. In this paper, the each different features from the left and right input image will be extracted by stereo vision system, and will be good for the 3-D recognition.

At present, information processing by computer is greatly concerned in our society. And robots controlled by computer are much introduced in a factory´s production line and so on, robot abilities develop robot obtain good results. And recently, robots greatly take part in not only limited place, for example a factory and so on, but also general a household. Some robots pleased people, others help humans task. Robots are sure to be great useful in nursing that as regarded our society as questionable. In this situation, we request that robots can take vision like human´s eyes ...

This study is a preliminary study to design a character automation system that considers the facial characteristics of mammals. The experimental data of this study was conducted on dogs (dog breeds) and humans, which were designed to be used in many contents. First, data was extracted from 100 types of dogs and 100 human data. Second, the criteria for measuring the ratio of important parts of the dog and human face were suggested. In addition, a comparative analysis of the face of a dog and a human face is conducted. Lastly, by analyzing the main component(PCA), the most characteristic elements in the faces of dogs and humans were analyzed. As a result, it was confirmed that the length of the face, the size of the eyes, the length of the glabellar, and the length of the glabellar and other parts are important. Through this study, the features of the dog's face that are different from humans are expected to contribute to the animal character automation.

The purpose of this study was to analyze the types of aesthetic characteristics and their expression methods in the goth style expressed with the sensibility of an illustrator, using the work of Toon Hertz as an example. As a research method for this purpose, previous studies and books were used to examine the components of fashion illustration, the concept and aesthetic characteristics of goth style, and the world of Toon Hertz's work. In the qualitative studies, Toon Hertz's works were collected and the characteristics of each component were analyzed. As a result of analyzing the aesthetic characteristics, Distortion appeared as the main element of the human body, and the human body was distorted through the method of combining the human body with animals, plants, and other objects. History was mainly expressed through fashion elements. Victorian clothing was predominant, the color was mainly black, and it was characterized by decorations, such as fancy laces, corsets, and shirrings. The screen layout and the object components appeared as the main components of mystery. Sensuality was a major component of the human body, and it emphasized decadent and sensual images of a woman sitting with both legs apart or placing her hands on her legs or chest. Fear was the main component of the human body, and strangeness and fear were created by omitting or removing parts of the body, such as women's arms, legs, hands, or eyes.

Using EEG, human physiological signal, as part of research which investigates the state of student learning and provides appropriate feedback to maximize learning efficiency, the relationship of learning attitude and analysis of EEG for female college student is presented. We study the reaction of learner's EEG using the concentration level extracted from the EEG power spectrum when students learn at various learning attitude. The experiment was conducted for the concentrating on learning and, as a control group, erratic attitude and closed eyes state. The attitude of concentrated Learning shows high concentration index and low relaxation index, where as the erratic attitude, such as eye movement and clicking, shows high level of attention index and noisy wave ratio. Especially, the state of closed eyes shows the ratio of alpha and theta wave under 1. This is distinct with open eyes cases.

This paper describes facial component detection and skew correction algorithm for face recognition. We use a priori knowledge and models about isolated regions to detect eye location from the face image captured in natural office environments. The relations between human face components are represented by several rules. We adopt an edge detection algorithm using sobel mask and 8-connected labelling algorith using array pointers. A labeled image has many isolated components. initially, the eye size rules are used. Eye size rules are not affected much by irregular input image conditions. Eye size rules size, and limited in the ratio between gorizontal and vertical sizes. By the eye size rule, 2 ~ 16 candidate eye components can be detected. Next, candidate eye parirs are verified by the information of location and shape, and one eye pair location is decided using face models about eye and eyebrow. Once we extract eye regions, we connect the center points of the two eyes and calculate the angle between them. Then we rotate the face to compensate for the angle so that the two eyes on a horizontal line. We tested 120 input images form 40 people, and achieved 91.7% success rate using eye size rules and face model. The main reasons of the 8.3% failure are due to components adjacent to eyes such as eyebrows. To detect facial components from the failed images, we are developing a mouth region processing module.

Eye tracking technology tracks human eyes movements to understand user's intention. This technology has been improving slowly and should be used for a variety of occasions now. For example, it enables persons with disabilities to operate a computer with their eyes. This article will show a typical implementation of an eye tracking system for persons with disabilities, after introducing the design principles and specific implementation details of an eye tracking system. The article discussed the realization of self-adapting regulation algorithm in detail. The self-adapting algorithm is based on feedback signal controlling the lens movements to realize automatic focus, and to get a clear eyes image. This CCD camera automatic focusing method has self-adapting capacity for changes of light intensity on the external environment. It also avoids the trouble of manual adjustment and improves the accuracy of the adjustment.
