Abstract

본 발명은 i) 혈관영상을 지역으로 구획한 뒤 각 지역내의 영상 픽셀 평균값 또는 표준편차값을 기반으로 지역별 임계값을 설정한 후 그 임계값을 기준으로 혈관과 비혈관을 분류하여 이진화하는 적응적 지역 이진화 처리단계; ii) 상기 적응적 지역 이진화 처리단계가 종료된 영상에 포함된 잡음을 보정하기 위해 모폴로지 연산하는 모폴로지 연산 처리단계; iii) 상기 모폴로지 연산 처리단계가 종료된 영상을 세선화하여 혈관라인을 추출하는 세선화 처리단계; iv) 상기 세선화 처리단계가 종료된 영상에서 각 지역 내 추출된 혈관라인의 방향을 파악한 뒤 혈관 방향에 직교하는 혈관의 그레이 프로파일을 분석하여 혈관의 두께를 측정하는 혈관의 방향 및 두께 측정단계; 및 v) 상기 단계 iv)에서 측정된 혈관의 방향 및 두께를 고려하여 지역마다 가장 적합한 가버 필터를 선택적으로 적용하는 적응적 가버 필터링 처리단계를 포함하는 혈관영상 처리방법에 관한 것이다.
