摘要：
PURPOSE: An apparatus and method for automatically segmenting a cartilage in a magnetic resonance image are provided to adaptively use brightness information and shape template according to appearance information in a patch by locally dividing an object.CONSTITUTION: A patch is generated around a boundary between an extracted bone and a cartilage(210). A segmentation is performed by using shape information and appearance information of the bone in each patch(220). The cartilage is obtained from the surface of the bone(230). A representation point is extracted among all boundary points. A patch is formed in the extracted representation point.COPYRIGHT KIPO 2013[Reference numerals] (200) Extracting a boundary between a bone and a cartilage (210) Generating a patch (220) Segmentation in each patch (230) Obtaining a cartilage (AA) Start (BB) Finish얇고 부분적인 변화가 심한 전체 연골 모양틀을 지역적인 부분들로 연골 형상을 나누어 세밀한 영역화를 수행하여, 사용자 입력이 전혀 없음에도 뼈와 연골의 경계를 분리해내는 과정이나, 패치 단위 영역화 과정을 통한 자기공명영상에서 연골 자동 영역화 장치 및 방법을 제공한다.
