Abstract

In this paper, we present an AAW(Adaptive Attention Window) based cell image segmentation method. For semantic AAW detection we create an initial Attention Window by using a luminance map. Then the initial AW is reduced to the optimal size of the real ROI(Region of Interest) by using a quad tree segmentation. The purpose of AAW is to remove the background and to reduce the amount of processing time for segmenting ROIs. Experimental results show that the proposed method segments one or more ROIs efficiently and gives the similar segmentation result as compared with the human perception.

본 논문에서는 적응적 관심영역(AAW: Adaptive Attention Window)에 기반한 세포영상 분할 기법을 제안한다. 적응적 관심영역은 분할하기 위해, 명암지도를 이용하여 초기 관심윈도우(IAW: Initial AW)를 생성한다. 생성된 초기 관심윈도우는 쿼드-트리 분할을 이용하여 실제의 관심영역(ROI: Region of Interest)과 유사한 크기가 될 때까지 축소된다. 이렇게 생성된 적응적 관심윈도우는 세포 영상에서 배경을 제거하고 관심영역 추출의 처리 시간을 줄이기 위해서 사용된다. 마지막으로 적응적 관심영역 안에서 영역을 분할하고, 관심영역만을 분리하기 위한 영역 병합과 제거를 수행한다. 실험에서 제안된 기법은 세포영상의 관심영역을 효과적으로 분리하여 인간 시각과 유사한 향상된 영상 분할 결과를 보여준다.
