초록

생물정보학분야에서 현미경을 통해 얻은 세포 영상은 생물학적 정보를 얻기 위한 중요한 지표이다. 연구자들은 영상을 육안으로 분석하기 때문에 분석에 많은 시간과 고도의 집중력이 요구된다. 게다가 연구자의 주관적 관점이 분석에 개입되어 결과를 객관적으로 정량화하는데 어려움이 있다. 따라서 본 연구에서는 OpenCV 라이브러리를 이용하여 세포의 자동 분석을 위한 HCS(High Content Screen) 알고리즘을 개발하였다. HCS 알고리즘은 이미지 전처리 과정, 세포 계수, 세포 주기와 분열지수 분석 기능을 포함한다. 본 연구에서는 공초점 레이저 현미경을 통해 얻은 위암세포(MKN-28) 영상을 분석에 사용하였으며, 성능 평가를 위해 세포영상 분석 프로그램인 ImageJ와 전문 연구원의 세포 계수 분석결과를 비교하였다. 실험 결과 HCS 알고리즘의 평균 정확성이 99.7%로 나타났다.

Microscope cell image is an important indicator for obtaining the biological information in a bio-informatics fields. Since human observers have been examining the cell image with microscope, a lot of time and high concentration are required to analyze cell images. Furthermore, It is difficult for the human eye to quantify objectively features in cell images. In this study, we developed HCS algorithm for automatic analysis of cell image using an OpenCV library. HCS algorithm contains the cell image preprocessing, cell counting, cell cycle and mitotic index analysis algorithm. We used human cancer cell (MKN-28) obtained by the confocal laser microscope for image analysis. We compare the value of cell counting to imageJ and to a professional observer to evaluate our algorithm performance. The experimental results showed that the average accuracy of our algorithm is 99.7%.
