In the online game, a game character to replace game player exists within the same game and it is very difficult to migrate to another on-line games. Also, players have taken a lot of time and effort in the character's growth. In recent years, it has raised many social side effects. Therefore, in order to solve these problems, this paper was implemented web services system based on previous studies for the migration of game character between different-type on-line game severs, and the proposed system verified through the experiment focused on 4 capability numerical value (money, HP:Hit Point, MP:Mana Point, level) between migration element of game character.

This paper presents a motion generation technique for arbitrary morphologies with the user defined correspondences between joints. Users can define the controlling part in the source character and the part to be controlled in the target character in our system. To remove the restriction in the morphology of the target character, we use the pair of example posture sets. In our system, in order to provide the correspondence regardless of the number of joints, the deformed part in the target character is simplified into the direction vector. The final postures are then generated with the weighted sum of the examples. Our experimental results demonstrate that our approach can generate motions for various target characters and can control the user defined joints in real-time.

The LPR(License plate recognition) system has been developed to efficient control for complex traffic environment and currently be used in many places. However, because of light, noise, background changes, environmental changes, damaged plate, it only works limited environment, so it is difficult to use in real-time. This paper presents a heuristic segmentation algorithm for robust to noise and illumination changes and introduce a real-time license plate recognition system using it. In first step, We detect the plate utilized Haar-like feature and Adaboost. This method is possible to rapid detection used integral image and cascade structure. Second step, we determine the type of license plate with adaptive histogram equalization, bilateral filtering for denoise and segment accurate character based on adaptive threshold, pixel projection and associated with the prior knowledge. The last step is character recognition that used histogram of oriented gradients (HOG) and multi-layer perceptron(MLP) for number recognition and support vector machine(SVM) for number and Korean character classifier respectively. The experimental results show license plate detection rate of 94.29%, license plate false alarm rate of 2.94%. In character segmentation method, character hit rate is 97.23% and character false alarm rate is 1.37%. And in character recognition, the average character recognition rate is 98.38%. Total average running time in our proposed method is 140ms. It is possible to be real-time system with efficiency and robustness.

In this paper, we realized a system that converts the character images of the printed Korean alphabet (Hangul) to the editable text documents by using the black and white CCD camera, We were able to abstract the contours information of the character which is based on the structural character by using the boundary tracing technique that is strong to the noise on the character recognition. By using the contours information, we recognized the horizontal vowels and vertical vowels of the character image and classify the character into the six patterns. After that, the character is divided to the unit of the consonant and vowel. The vowels are recognized by using the maximum length projection. The separated consonants are recognized by comparing the inputted pattern with the standard pattern that has the phase information of the boundary line change. We realized a system that the recognized characters are inputted to the word editor with the editable KS Hangul completion type code.

In the steel production line, the molten metal of a furnace is transformed into billet and then moves to the heating furnace of the hot rolling mill. This paper describes about the development of recognition system for the characters, which was marked at the billet material by use template-marking plate and hand written method, in the steel plant. For the recognition of template-marked characters, we propose PSVM algorithm. And for the recognition of hand written character, we propose combination methods of CCD algorithm and PSVM algorithm. The PSVM algorithm need some more time than the conventional KLT or SVM algorithm. The CCD algorithm makes shorter classification time than the PSVM algorithm and good for the classification of closed curve characters from Arabic numerals. For the confirmation of algorithm, we have compared our algorithm with conventional methods such as KLT classifier and one-to-one SVM. The recognition rate of experimented billet characters shows that the proposing PSVM algorithm is 97 % for the template-marked characters and combinational algorithm of CCD & PSVM is 95.5 % for the hand written characters. The experimental results show that our proposing method has higher recognition rate than that of the conventional methods for the template-marked characters and hand written characters. By using our algorithm, we have installed real time character recognition system at the billet processing line of the steel-iron plant.

The purpose of this study was to suggest the earth science lesson model based on the creativity character education. To conduct this study, the curriculum revision in 2009 was analyzed by the causal mapping method. One after another, the creativity character education and earth system education were analyzed by the same method. Through as mentioned above, the key words which have relating concepts each other were picked out. Lastly, the key words were connected and compounded for the earth science lesson model based on the creativity character education. The model indicates that the earth science lesson based on the creativity character education requires the reconstructs of the processing and contents of the lesson. In other words, the teaching/learning must be progressed as corresponding between scientific facts and mental recognition, scientific concepts and compounding thinking skill, scientific laws and reconstructing thinking skill. In contents were reconstructed as relating to knowledge, creativity, characters and guidance counseling. The results of this study suggested the earth science lesson model based on the creativity character education needs developing and applying teaching/learning materials and managing discussing and cooperative learning.

Due to the rapid development of mobile devices equipped with cameras, instant translation of any text seen in any context is possible. Mobile devices can serve as a translation tool by recognizing the texts presented in the captured scenes. Images captured by cameras will embed more external or unwanted effects which need not to be considered in traditional optical character recognition (OCR). In this paper, we segment a text image captured by mobile devices into individual single characters to facilitate OCR kernel processing. Before proceeding with character segmentation, text detection and text line construction need to be performed in advance. A novel character segmentation method which integrates touched character filters is employed on text images captured by cameras. In addition, periphery features are extracted from the segmented images of touched characters and fed as inputs to support vector machines to calculate the confident values. In our experiment, the accuracy rate of the proposed character segmentation system is 94.90%, which demonstrates the effectiveness of the proposed method.

In the transmission system, the transmission efficiency can be increased by applying the proper character coding method. This paper is to show the character coding rule in computer and information equipment etc to improve the transmission efficiency in datacommunications. The character coding rule showing in this paper was suggested by considering the two view points. First one is FLAG bits in HDLC and PPP protocol on datalink layer in OSI 7 layer. Second one is one of the scrambling method, HDB-3, on physical layer in OSI 7 layer. The former is to prevent the sequence of over 5bits of "1" in the character codes. The latter is to prevent the sequence of over 4bits of "0" in the character codes.
