In this paper, a new method of phoneme segmentation of handwritten Korean characters using the local graph pattern is proposed. At first, thinning was performed before extracting features. End-point, inflexion-point, branch-point and cross-point were extracted as features. Using these features and the angular relations between these features, local graph pattern was made. When local graph pattern is made, the of strokes is investigated on contacting point. From this process, pattern is simplified as contacting pattern of the basic form and the contacting form we must take into account can be restricted within fixed region, 4therefore phoneme segmentation not influenced by characters form and any other contact in a single character is performed as matching this local graph pattern with base patterns searched ahead. This experiments with 540 characters have been conducted. From the result of this experiment, it is shown that phoneme segmentation is independent of characters form and other contact in a single character to obtain a correct segmentation rate of 95%, manages it efficiently to reduce the time spent in lock operation when the lock.

Like CPUs, regular expression processors that perform regular expression pattern matching using instructions have been proposed recently. Of these, only REMPc provides features for character class matching. In this paper, we propose an architecture for efficient character class matching in a regular expression processor, which use character class bitmap format in a instruction operand field and implement the hard-wired character class comparator for several frequently used character classes. Using the proposed method, most of the character classes used in Snort rule can be represented by an operand or an instruction. Thus, character class matching can be performed more efficiently in the proposed archiecture than in REMPc.

In this paper, a new segmentation method of machine printed character string with arbitrary length is proposed. Character recognition requires character segmentation as a previous step. However character segmentation itself requires a character recognition capability for less error segmentation. It is necessary to attack both these problem simultaneously. It is proposed that a new recognition-based segmentation method, which recognizes a character in touching characters with help of defined side-profiles. The match of ‘side-profiles of touching characters' with ‘side-profiles of prototypes' gives single character candidates in touching characters. It segments touching characters according to cutting costs.

In this study, I examined the relationship between the pattern of Tungp'o (東坡体)'s characters play, Paza(破字) and Nanji(難字), Iruiimyo(異類異名) the Chinese characters play, developed in the Edo period in Japan. I found out the following. First, Nanji and Iruiimyo's method of Chinese character transformation is like Tungp'o(東坡体)'s characters play and Paza(破字), that is to make an analysis of Chinese character. For example, to extend or shorten to character's length, and to increase or reduce the character's size. And, I also found out there is no block type characters play in Nanji and Iruiimyo. Second, I also found that the similarity of the method of Chinese character transformation between the pattern of Tungp'o(東坡体)'s characters play, Paza(破字) and Nanji(難字), Iruiimyo(異類異名). The method of to flip character (180 degrees) and to letting character lie down (90 degrees) is very similar each other. But there is no method to make incline of character (45 degrees) in Nanji and Iruiimyo. Third, I found that the method to extract part of character also exists in Chinese and Japanese characters play. And, I also found that the method to decompose characters in half from the pattern of Tungp'o(東坡体)'s characters play, but I can't find this method from Nanji and Iruiimyo. To decompose characters in half is very like the method of paja. So, we can understand that Nanji and Iruiimyo is located in the middle stage of the pattern of between Tungp'o(東坡体)'s characters play and Paza(破字).

In the ubiquitous computing age which uses a high quantity network, mobile devices such as wearable and hand-held ones with a small tamers and a wireless communication module will be widely used in near future. Thus, a lot of researches about an augmented game on mobile devices have been attempted recently. The existing augmented games used a traditional 'backpack' system and a pattern marker. The 'backpack' system is expensive, cumbersome and inconvenient to use, and because of the pattern marker, it is only possible to play the game in the previously installed palace. In this paper, we propose an augmented game called Flying Cake using a face region to create the virtual object(character) without the pattern marker, which manually indicates an overlapped location of the virtual object in the real world, on a small and mobile PDA instead of the cumbersome hardware. Flying Cake is an augmented shooting game. This game supplies us with two types: 1) a single player which attacks a virtual character on images captured by a camera in an outdoor physical area, 2) dual players which attack the virtual character on images which we received through a wireless LAN. We overlap the virtual character on the face region using a face detection technique, and users play Flying Cake though attacking the virtual character. Flying Cake supplies new pleasure to flayers with a new game paradigm through an interaction between the user in the physical world captured by the PDA camera and the virtual character in a virtual world using the face detection.

Many hardware-based regular expression matching architectures are proposed for high performance matching. In particular, regular expression processors such as ReCPU and SMPU perform pattern matching in a similar approach to that used in general purpose processors, which provide the flexibility when updating patterns. However, these processors are inefficient in performing class matching since they do not provide character class matching capabilities. This paper proposes an instruction set and architecture of a regular expression matching processor, which can support character class matching. The proposed processor can efficiently perform character class matching since it includes character class, character range, and negated character class matching capabilities.

The purpose of this study is to analyze the composition for visual character to make the process of television programs. The study can be classified as a visual communication methods into a target audiences. At the beginning of using visual character was communication method as an insufficiency of television programs. However, In recent years, television industry using visual character in many ways into television programs that it can be classified not only to developed the communication method as a function of effects, but also to changed substitute a variety of graphic pattern of visual character in television programs. As a matter of fact, this study have some implication in terms of using a visual character to making television program, therefore, the results show that different ways of using visual character into the diversity of television programs were discussed.
