1 Face Recognition
인식 Detection
HOG 알고리즘
밝기가 변하는 방향만 고려
이미지의 패턴을 알수있음주변픽셀과비교해서얼마나어두운지비교
이미지가어두워지는방향으로화살표그림
1 Face Recognition
얼굴의위치교정및투영
Face area detected in image The perfectly centered result we want
Face landmarks detected Face transformed to be as close as possible to perfectly centered
얼굴이옆으로돌아가있어도눈과입을이미지상에서대략
동일한위치에맞출수있음
2 EXO Face Recognition
데이터수집
장애물 1. 엑소멤버들의얼굴을구분할수가없다.
‘AI에게 EXO 오빠들의얼굴을학습시키기엔나에게안면인식장애가…’
1차데이터모으기실패
2 EXO Face Recognition
데이터수집
해결책 1. EXO의팬심
“우리에겐컴퓨터보다월등한, 멤버들별로사진들을보관해두는
수만명의엑소팬이있다.”
