Investigation of visual features for age perception

얼굴인식에서 연령 추정을 위해 사용되는 시각적 특징 요소를 확인하기 위해 세 편의 실험이 수행되었다. 실험 1에서는 연령 지각에서 제시시간에 따른 눈, 코, 입 각 구성요소의 효과를 비교하였다. 실험 2에서는 제시 시간별로 공간주파수 필터링의 효과를 살펴보았다. 실험 3에서는 연령지각에서도 얼굴 외곽선의 효과와 역위 제시 효과가 나타나는지 알아보았다. 실험 결과 눈만 길게 제시한 경우는 전체 얼굴을 모두 제시한 경우 못지않게 연령 추정을 잘하였지만 눈만 짧게 제시하거나 코나 입만 제시한 경우는 제시시간에 관계없이 연령 추정을 잘 못하는 것으로 나타났다. 또한 제시시간에 관계없이 낮은 공간주파수 필터링이나 높은 공간 주파수 필터링은 모두 연령 추정에 영향을 미치는 것으로 나타났으며 외곽선이 없는 경우보다 위-아래가 뒤집힌 경우가 연령지각에 더 큰 영향을 미치는 것으로 나타났다. 이러한 결과는 연령 지각은 전체형태 처리와 세부특징 처리 모두에 의해 일어나지만 전체 형태 처리가 더 중요하다는 것을 의미하며 짧은 제시시간에도 빠르게 처리될 수 있음을 시사한다.

Abstract

Three experiments were conducted to identify visual features for age perception. Effects of display time of eye, nose, and mouth, spacial frequency filtering, face outline and inversion on age perception were examined in experiments 1, 2, & 3. Results showed that age estimation was accurate either when eyes were presented for a longer duration or when a whole face was presented. However, age estimation was not accurate when eyes were presented only for a short period of time or when nose or mouth was presented. Also, both high and low frequency filtering did affect age estimation regardless of display time. And face inversion was more influential than face outline on age perception. These results suggest that age perception rely heavily on configurational than featural process.
