| Zusammenfassung: | One embodiment of the present invention discloses a method for identifying fake videos using remote photoplethysmographic signals, which includes the steps of: acquiring a video; setting and extracting a first area and a second area from the acquired video; calculating remote photoplethysmographic signals (remote PPG signals) for the extracted first and second areas, respectively; and comparing processing results of the extracted remote photoplethysmographic signal of the first area and the extracted remote photoplethysmographic signal of the second area to determine whether the acquired video is a fake video.
본 발명의 일 실시 예는, 영상을 획득하는 단계; 상기 획득된 영상에서 제1영역 및 제2영역을 설정하여 추출하는 단계; 상기 추출된 제1영역 및 제2영역에 대한 원격 광용적맥파신호(remote PPG signal)를 각각 산출하는 단계; 및 상기 추출된 제1영역의 원격 광용적맥파신호 및 상기 추출된 제2영역의 원격 광용적맥파신호의 처리결과를 서로 비교하여, 상기 획득된 영상이 가짜 동영상(fake video)인지 여부를 판단하는 단계;를 포함하는, 원격 광용적맥파신호를 이용한 가짜 동영상 판별 방법을 개시한다. |
