접촉한 얼굴 검색

얼굴 연락처 검색 기능은 지정된 시간 동안 특정 인물과 접촉한 모든 사람을 아카이브에서 찾아줍니다.

검색 알고리즘은 다음과 같이 작동합니다.

1. 업로드한 사진 속 사람과 비슷하게 생긴 모든 사람을 아카이브에서 찾습니다.
2. 사진 속 인물과 다른 사람들이 함께 등장하는 아카이브 자료 조각을 분석합니다.

To search for face contacts, do the following:

1. Set the search interval (검색 간격 설정 참고).
2. Set the minimum similarity level (in %) between the face in the photo and the faces from the archive (1). If the similarity level is below the set value, these results will be ignored during the search.
   
3. Select a photo of the person whose contacts you want to find (2). Supported formats: png, jpg, jpeg, jpe. When you click the face in the surveillance window, this face will be selected for search. If you do not select a photo, then all faces recognized during the specified time will be displayed. To delete a photo from the search, click the button.
4. Set the minimum contact time of other persons in the frame with the person on the photo in the MM:SS format (3). If the contact time is below the specified value, these results will be ignored during the search. The maximum contact time is 59 seconds.

5. Click the Search button.

   Note

   Once launched, the search can be stopped at any time. To do this, click the Stop button which appears in place of the Search button.

This starts a search based on the defined criteria.

The search results panel will display video frames that contain persons who contacted with the person on the photo. Recognized faces will be highlighted with a red frame.

To instantly export a face image from the frame, do the following:

1. Click a face track in the surveillance window.
2. Click the button (4). 

The face image will be saved to the folder specified in the settings (see 내보내기 옵션 구성).
