이 노트북은 MoveNet 및 TensorFlow Lite를 사용하여 포즈 분류 모델을 훈련하는 방법을 알려줍니다. 결과는 MoveNet 모델의 출력을 입력으로 받아들이고 요가 포즈의 이름과 같은 포즈 분류를 출력하는 새로운 TensorFlow Lite 모델입니다.
이 노트북의 절차는 세 부분으로 구성됩니다.
- 파트 1: 포즈 분류 훈련 데이터를 실제 포즈 레이블과 함께 MoveNet 모델이 감지한 랜드마크(신체 키포인트)를 지정하는 CSV 파일로 사전 처리합니다.
- 2부: CSV 파일의 랜드마크 좌표를 입력으로 사용하고 예측된 레이블을 출력하는 포즈 분류 모델을 빌드하고 훈련합니다.
- 3부: 포즈 분류 모델을 TFLite로 변환합니다.
기본적으로 이 노트북은 요가 포즈라는 레이블이 지정된 이미지 데이터 세트를 사용하지만, 포즈의 이미지 데이터 세트를 업로드할 수 있는 섹션도 파트 1에 포함했습니다.
TensorFlow.org에서 보기 | Google Colab에서 실행 | GitHub에서 소스 보기 | 노트북 다운로드 | TF 허브 모델 보기 |
준비
이 섹션에서는 필요한 라이브러리를 가져오고 랜드마크 좌표와 정답 레이블이 포함된 CSV 파일로 훈련 이미지를 사전 처리하는 여러 함수를 정의합니다.
여기서 관찰할 수 있는 일은 없지만 숨겨진 코드 셀을 확장하여 나중에 호출할 일부 기능에 대한 구현을 볼 수 있습니다.
모든 세부 사항을 모르는 상태에서 CSV 파일만 생성하려면 이 섹션을 실행하고 1부로 진행하십시오.

랜드마크 좌표를 사용하고 입력 이미지의 사람이 수행하는 포즈 클래스를 예측하는 TensorFlow 모델을 빌드합니다. 모델은 두 개의 하위 모델로 구성됩니다.

- 서브 모델이 피드는 몇 가지를 통해 내장 포즈
