Improved Lung and Pulmonary Vessels Segmentation and Numerical Algorithms of Necrosis Cell Ratio in Lung CT Image Open
흉부 CT 영상에서 폐 질환의 진단을 위해서 폐 분할, 폐혈관 분할과 폐 질환 부위에 대한 괴사 세포 비율의 수치적 계산을 제안 하였다. 첫 번째 단계는 흉부 CT 영상에서 3차원 레이블링 기법과 3차원 영역 성장법을 적용하여 폐와 기관지를 분리한다. 두 번째 단계는 폐혈관 분할은 1차 다항식 회귀(Polynomial Regression)를 사용한 변화율을 적용 하여 분할한 다음, 잡음 제거를 실시하여 최종의 폐혈관을 분할한…
