마이크로프로세서 시스템의 키보드 버튼의 누름 결과를 기존의 입력 스캔 제어방법이 아닌 인터럽트 제어방법으로 시도하였다. 키보드 스캔 결과를 인터럽트 제어 방법으로 제어 시 적절한 30ms의 주기로 인식하도록 함으로써 마이크로프로세서의 작업부하를 줄이는 키보드 버튼 누름 제어 인식 알고리즘을 제시하였다.

PD in defects of solid insulation system is very harmful since it leads to deteriorate insulation system by. the discharge electrons and ions bombarding the insulation surface and the action of chemical products that are formed by discharges. PD is used to detect and recognize defects and degradation of insulation system However, there are still marked difficulties to recognize defects by PD methode. In this paper, we investigated properties of PD of defects in solid insulation by using statical methods and classified PD patterns of surface discharge, electrical tree and void discharge with source of discharge, we used specific distributions such as $H_n(q)$, $H_{an}(\phi)$, $H_n(\phi)$, $H_a(\phi)$ to recognize defects of solid insulation system.

Mountains have been playing an important role in the Japanese culture. It is important from landscape planning perspectives to maintain mountains in the proximity of cities. In this thesis, the geographical perception of residents in Kohoku New Town has been studied. Geographical changes before and after the Kohoku New Town development were clarified first. Following these clarifications, interviews with residents who moved into the area before and after the development were conducted. In this investigation, the interviewees were asked about mountains, valleys, hills, and slopes; and the areas that they recognize on the map were then specified. From these results, the mountain area which residents recognize and the actual geographical features were compared. The geographical characteristics of the mountains that the residents recognize were revealed, and the perception of mountains was defined. Not only did geographical features and vegetation affect the perception of mountains, but also residents' personal experiences were important. As a result, new information for future geographical landscape planning has been obtained.

자동차 번호판 인식 시스템에서 가장 중요한 요소는 자동차 이미지 영역에서 번호판 영역을 추출, 추출된 영역에서 문자추출, 추출된 문자의 인식등의 과정이다. 본 논문은 자동차 번호판 인식과정에서 적응 알고리즘을 이용하여 보다 정확한 인식이 될 수 있도록 한다. 본 논문에서 사용하는 적응 알고리즘은 기존의 방식과는 달리 특정한 알고리즘을 이용하여 인식을 하지 않고 다양한 알고리즘을 이용한 인식 결과의 조합으로 최적의 해법을 찾는다. 번호판 인식을 위한 적응 알고리즘은 원형 정합 알고리즘, 벡터 알고리즘, 세선화 알고리즘 등이다. 적응 알고리즘을 이용한 실험 결과 자동차 이미지에 대해서 90% 이상 인식이 가능함을 확인할 수 있었다.

A service robot is expected to be useful in indoor environment such as a hotel, a hospital and so on. However, many service robots are driven by wheels so that they cannot climb stairs to move to other floors. If the robot cannot use elevators. In this paper, the mobile manipulator system was developed, which can operate numeral buttons on the operating panel in the elevator. To perform this task, the robot is composed of an image recognition module, an ultrasonic sensor module and a manipulator. The robot can recognize numeral buttons and an end-effector in manipulator by the vision system. The Learning vector quantization (LVQ) algorithm is used to recognize the number on the button. The barcode mark on the end-effector is used to recognize the end-effector. The manipulator can push numeral buttons using informations captured by the vision system. The proposed method is evaluated by experiments.

This paper proposes a new image processing algorithm to recognize korean documents. It take out the region of text area form input image, then it makes esgmentation of lines, words and characters in the text. A precision segmentation is very important to recognize the input document. The input image has 8-bit gray scaled resolution. Not only the histogram but also brightness dispersion graph are used for segmentation. The result shows a higher accuracy of document recognition.

In this paper, we suggest the 3D Vision Inspection Algorithm which is based on the external shape feature, and is able to recognize the object. Because many objects made by human have the regular shape, if we posses the database of pattern and we recognize the object using the database of the object's pattern, we could inspect the objects of many fields. Thus, this paper suggest the 3D Vision inspection Algorithm using the Geometrical Pattern Matching by making the 3D database.

In this paper, a technique to reduce the computational effort of Hough Transform used to recognize digital circles is proposed. The technique, which is a version of the Hough Transform uses bisectors of circles cords to estimate the center of circles. This system which is implemented in this paper gets center, radius, thickness of circular fiducials regardless of input form. This system uses fuzzy set theory which deals with 'ambigousness', In order to recognize imprecise circular fiducial.

This paper proposes a new image processing algorithm to recognize korean documents. It take out the region of syllable area from input character image, then it makes recognition of a consonant and a vowel in the character. A precision segmentation is very important to recognize the input character. The input image has 8-bit gray scaled resolution. Not only the shape but also vertical and horizontal lines dispersion graph are used for segmentation. Theresult shows a higher accuracy of character segmentation.
