개요

본 논문은 fMRI 데이터로부터 자연 이미지를 재구성하는 문제를 다룹니다. 기존의 두 단계 모델(VAE와 확산 모델 결합)은 모든 공간 주파수 성분을 동일하게 처리하여 효율성이 떨어지는 한계가 있었습니다. 본 논문에서는 공간 주파수 대역을 선택적으로 필터링하는 경량의 적응형 모듈인 FreqSelect를 제안합니다. FreqSelect는 뇌 활동과 관련된 주파수를 강조하고 무관한 주파수를 억제함으로써 이미지 특징과 자연 데이터 사이의 콘텐츠 인식 게이트 역할을 수행합니다. Natural Scenes 데이터셋을 사용한 평가 결과, 저수준 및 고수준 지표 모두에서 재구성 품질을 향상시켰으며, 학습된 주파수 선택 패턴은 뇌에서 다양한 시각 주파수가 표현되는 방식에 대한 해석 가능한 통찰력을 제공합니다. 또한, 피험자와 장면에 걸쳐 일반화되며 다른 신경 영상 기법으로 확장될 가능성이 있습니다.
