이중 문턱 값과 적분영상을 이용한 2차원 바코드 영상의 적응적 이진화

이연경,유훈,Lee, Yeon-Kyung,Yoo, Hoon 한국정보통신학회 2012 한국정보통신학회논문지 Vol.16 No.11

본 논문에서는 2차원 바코드 영상을 위한 적응적 이진화 방법을 제안한다. 적응형 이진화 방법은 조명의 영향을 최소화하여 이진화를 수행하는 기술이다. 적응적 이진화 방법은 주로 문서 영상에 맞게 발전되어 왔다. 기존 방법들은 적응적 이진화에서 사용되는 박스에 대한 크기 설정 문제를 가지고 있다. 이 문제로 기존 방법들은 이차원 바코드 영상 인식에 적용하기에 부적절하다. 문제점을 극복하기 위해 먼저 박스크기와 기존 방법들의 문제점을 분석하고, 이를 기반으로 적분영상을 사용한 새로운 적응형 이진화 방법을 소개한다. 제안한 방법의 성능 입증을 위해 기존의 방법과 속도, 성능 비교 실험을 수행하였고 실험 결과는 기존 방법보다 우수함을 입증하였다. In this paper, we propose an adaptive thresholding method to binarize two-dimensional barcode images. Adaptive thresholding methods that minimize light effects convert an original image into a binary image. The methods are applied to document image binarization. The methods, however, have problems of determining box size used in adaptive thresholding. thus, they inappropriate to use in recognition of two-dimensional barcode images. To overcome the problem, we analysis the problem and propose a new adaptive threshold method using the integral image. To show the effectiveness of our method, we compared our method with the well-known existing methods in terms of visual quality and processing time. The experimental result indicates that the proposed method is superior to the existing method.

Since 1939, Bupeyong was rapidly urbanized and industrialized for the purpose of constructing military logistics base of the empire of Japan. Based on Kyungin urban planning of 1940 and industrial land development plan of Kyeonggido, many military factories and arsenal were constructed, and great amount of housing were also built for their workers from 1939 to 1944. Although the initial urban planning was unfinished, urban change from rural area to military industrial city in the late Japanese colonial era, made identity of city of Bupyeong. Workers houses which built during five years vary in different size and type, and somewhat reflects discussions about housing attempts to solve the housing shortage. This study aims to analyze architectural characteristics of workers housing related with discussions of housing, and to evaluate its value as an industrial heritage which constitute the urban landscape of the industrial city of Bupyeong. Workers houses in Bupyeong were constructed by military factories, construction company, and Chosun housing administration, with land readjustment planning. As the war became serious, workers housing became smaller and simpler. Construction of workers housing was essential part of modern military industrial city, bupyeong, and many of workers housing are still remained whereas most of factories were demolished, thus workers housing of bupyeong has significant meaning as industrial heritage of Bupyeong.

네 방향 스캔 방법을 이용한 QR코드 파인더 인식

이연경,유훈,Lee, Yeon-Kyung,Yoo, Hoon 한국정보통신학회 2012 한국정보통신학회논문지 Vol.16 No.6

본 논문에서는 네 방향으로 스캔 방향을 늘려 QR코드 파인더를 인식하는 방법을 제안한다. QR코드 인식의 첫 과정은 파인더 인식이다. 만약 파인더를 인식하지 못한다면 QR코드를 인식 할 수 없다. 기존의 QR코드 인식방법은 정면에서 촬영하지 않으면 QR코드를 인식하지 못한다는 문제점을 가지고 있다. 이러한 문제점을 극복하기 위해서 네 방향으로의 스캔과 후보군 영상을 사용하여 정확하게 파인더의 위치를 찾는다. 또한 모폴로지 연산을 이용하여 파인더의 위치를 다시 추려낸다. 제안된 방법을 입증하기 위해 기존의 인식 방법과 비교 실험을 수행하였고 그 결과 제안한 방법이 기존 방법보다 QR코드 파인더 인식률에서 우수함을 입증하였다. This paper describes a method to detect QR-code finders by four-direction scanning. The finder recognition is the first step in the QR-code recognition. If the finder is missing, QR-code recognition fails. The existing QR-code recognition method has a problem that the recognition performance decreases for perspectively distored images. To overcome the problem, we introduce four-direction scanning and a candidate set image to accurately detect QR-code finders. Using morphological operations detect the QR-code finder in the candidate set image robustly. To show the effectiveness of our method, we compared our method with the well-known existing method. The experimental result indicates that the proposed method is superior to the existing method in terms of the finder recognition performance.

Since 1882 when Korea government permitted the foreign residents in Seoul, Japanese have resided in the Jingogae district on northern part of Namsan(南山). With the growing power of Japan in Korean peninsula, Japanese have expanded their residential area, which has affected the changes of urban environment of Seoul. Especially, street environment in the Japanese settlement was improved along with urban improvement works, including water and sewer infrastructure and urban improvement, and establishment of street facilities. The street environment improvement project for Japanese settlement, which was initiated in 1895 and continued to 1910, was aimed at improving its transportation, sanitation, and business. Urban improvement works in Japanese settlement before 1910 has changed the street environment of southern part of Seoul, and affected the transformation of urban changes of Seoul after 1910. Additionally, it is meaningful that these changes of street environment in Japanese settlement were done before colonization, thus urban improvement work in Japanese settlement should be considered in social issue as well as physical environmental issue. Consequently, changes of street environment in Japanese settlement are deeply related with modernization and colonization of Seoul before 1910.

Since 1876 when Korea opend its port to foreign countries, Japanese merchants have begun their business in Korea. In case of Seoul, most of their shops were located in Japanese settlement on northern part of Namsan(南山). In the early days of settlement, business community was small with few retail shops selling basic commodities to Japanese residents. However, it has rapidly expanded with the increased number of stores as well as bigger size stores as the Japanese residents increased and Koreans and westerners join the customer group as trade between Korea and Japan has grown. Japanese stores were located mainly in the Honmachi(本町) 4~5th Street, in the early period of residence, but they expanded their base to the main business district of Seoul such as Namdaemunro after Sino-Japanese war. Major streets of the residential area, including Honmachi Street, were surrounded by unique Japanese commercial buildings such as newly built Machiya(町屋) and Western style stores, along with Japanese commercials and decoration.

울산 한국석유공업사택을 중심으로 본 1960년대 울산의 도시주거와 내국인용 사택의 특징

이연경(Lee, Yeon-Kyung) 대한건축학회 2023 대한건축학회논문집 Vol.39 No.10

The Korea Petroleum Group Housing in Yaeum-dong, Ulsan, built in 1966, is the city’s oldest remaining company housing. Ulsan experienced rapid industrialization after being designated as a Korean industrial center in 1962. To accommodate the growing population of factory workers, various residential quarters were developed, including company housing, public housing, land readjustment projects, and housing for those displaced by industrial developments. Company housing is a distinctive feature of Ulsan, divided into housing for foreign engineers and housing for Korean employees. The Korea Petroleum Group Housing primarily served Korean managers and executives. Unlike housing for foreign engineers, it lacks boundaries and community facilities, following the standard design of 1960s public housing. This makes it a representation of Ulsans original company housing for Koreans, built prior to the completion of urban planning. Furthermore, its a significant urban heritage within Ulsans industrial landscape, reflecting the citys industrial urbanization process. Its relatively well-preserved state is noteworthy, considering the removal of most company housing structures.
