Abstract

GAN을 이용한 의료 영상의 광강도 분포 일반화 기법이 개시된다. 일 실시예에 따른 광강도 분포 일반화 시스템에 의해 수행되는 광강도 분포 일반화 방법은, 의료 영상에 대한 의료 영상에 대한 학습 데이터 셋의 광강도 분포와는 다른 분포를 갖는 새로운 데이터 셋이 입력됨을 수신하는 단계; GAN(Generative adversarial network)에 기반하여 상기 수신된 새로운 데이터 셋의 광강도 분포를 조절하는 단계; 및 상기 광강도 분포가 조절된 새로운 데이터 셋을 상기 학습 데이터 셋으로 학습된 분류 네트워크를 통과시켜 분류 결과를 획득하는 단계를 포함할 수 있다.
