이광욱,단병규,김승균,고성제,Lee, Kwang-Wook,Dan, Byung-Kyu,Kim, Seung-Kyun,Ko, Sung-Jea 한국전기전자학회 2009 전기전자학회논문지 Vol.13 No.2

언샤프 마스킹 기법은 회색조 영상의 화질 향상을 위해 널리 사용되는 영상 강화기법 중 하나이다. 하지만 언샤프마스킹 알고리즘은 노이즈에 민감하며 오버/언더슛이 발생하여 영상을 열화시키는 문제가 있다. 또한 칼라 영상성분에 기존 알고리즘을 그대로 적용하게 되면 영상에서 색차의 왜곡현상이 발생한다. 이러한 여러 가지 문제를 해결하기 위하여 본 논문에서는 고급 언샤프 마스킹 알고리즘을 사용하여 색차왜곡 없이 영상의 경계를 강조하고 노이즈와 오버/언더슛 문제를 해결한다. 제안하는 알고리즘은 오버/언더슛과 노이즈 문제를 해결하기 위하여 인간의 시각적 특성과 영상의 지역적 색차 대비 특성을 이용하여 영상 강화의 단계를 조절하고, RGB영상과 HSI영상의 관계를 바탕으로 RGB의 벡터적 특성에 기반한 투사 방법을 이용하여 색차왜곡을 방지한다. 실험 결과는 제안하는 알고리즘이 성공적으로 경계 영상을 강조하는 동시에 타 알고리즘을 적용했을 때 발생하는 색차왜곡과 노이즈 및 오버/언더슛 현상 없이 영상이 강조된다는 것을 확인할 수 있다. Unsharp masking is a popular image enhancement technique used to sharpen an image appearance in gray images. However, the conventional unsharp making techniques amplify the noise and easily cause overshoot artifacts. Moreover, the unsharp masking tends to introduce color distortion when it is applied to the each color component independently. To solve these problems, we propose a novel unsharp masking technique based on human visual system and vector projection. The proposed algorithm consists of two steps. First, the proposed algorithm controls the level of sharpening by exploiting the characteristics of the human visual system and contrast region. Then the vector projection is applied to remove the color distortion. Experiment results show that our proposed algorithm successfully produces sharpened images that are free of noise and color distortion commonly found in the conventional unsharp masking algorithms.

Google의 새로운 개인정보정책의 법적 문제점

이광욱(Kwang-Wook Lee) 서울대학교 법학평론 편집위원회 2012 법학평론 Vol.3 No.-

개인정보의 경제적 가치가 중요하게 됨과 비례하여 개인정보의 유출 등 침해 사고도 빈발하고 있고, 정보주체의 개인정보에 대한 권리 침해 가능성도 증대되었다. 이러한 배경 아래 우리나라에서도 2011. 9. 30. 개인정보 보호에 관한 일반법인 「개인정보 보호법」이 시행되었고, 2012. 4. 1.부터는 본격적으로 시행되고 있다. Google의 새로운 개인정보 정책의 문제점을 다루는 이 글은 위와 같은 사회적, 경제적, 법제적 배경 아래 Google이라는 거대 IT 기업의 개인정보 정책의 변경이 정보주체에 대하여 어떠한 권리침해 등 법적 위험을 가져올 수 있는지를 살펴보고, 이를 어떻게 규제할 것인지 고민해 보는 의도에서 작성되었다. Google의 새로운 개인정보 정책은 「개인정보 보호법」과 「정보통신망 이용촉진 및 정보보호 등에 관한 법률」에서 정한 개인정보 취급방침에 관한 사항, 목적 외 이용 금지, 최소수집원칙 등 개인정보 보호 원칙, 동의 절차 등 규정과 「약관의 규제에 관한 법률」을 위반하였거나 부합하지 않고, Google 서비스 이용자의 자기정보결정권 등 권리를 침해할 가능성이 있다. 현행 법의 한계 등으로 규제 기관이 제대로 된 규제를 하고 있지 못하고 있으나, 향후에는 적극적인 법 해석으로 정보주체의 권리보장에 부족함이 없는 조치가 있기를 기대해 본다. As the significance of the economic value of personal information has increased, occurrences of leakage and infringement of personal information have also increased, and, this in turn has also increased the likelihood of infringing upon the rights of the data subject. Under such circumstances, the Personal Information Protection Act (the “PIPA”), which is a general law that protects personal information, became effective as of September 30, 2011 in Korea and, as of April 1, 2012, the PIPA is being fully implemented. This article which deals with issues regarding Google’s new privacy policy, examines the risks of infringing upon the rights of the data subject and legal risks which are faced under the societal, economic and legal background noted above and explores possible methods to regulate the above. Google’s new privacy policy either violates or is inconsistent with the regulations of the PIPA and the Act on Promotion of Information and Communications Network Utilization and Information Protection with respect to matters such as policies for handling personal information, prohibition of use beyond the purpose of collection, principle of collecting the minimum amount of information necessary, the principle of protecting personal information and the procedures for obtaining consent. Moreover, Google’s new privacy policy also violates or is inconsistent with the Regulation of Standardized Contracts Act and may violate the right to decide matters by Google service user regarding his/her information. While the applicable authorities are limited in regulating the above due to, among other factors, limitations under the current laws, it is possible that sufficient measures to protect the rights of the data subject could be made through active interpretation of the laws.
