텐서플로우:: 작전:: 디코드Png
#include <image_ops.h>
PNG로 인코딩된 이미지를 uint8 또는 uint16 텐서로 디코딩합니다.
요약
attr channels
디코딩된 이미지에 대해 원하는 색상 채널 수를 나타냅니다.
허용되는 값은 다음과 같습니다.
- 0: PNG로 인코딩된 이미지의 채널 수를 사용합니다.
- 1: 회색조 이미지를 출력합니다.
- 3: RGB 이미지를 출력합니다.
- 4: RGBA 이미지를 출력합니다.
필요한 경우 PNG로 인코딩된 이미지는 요청된 색상 채널 수와 일치하도록 변환됩니다.
이 작업은 인터페이스가 동일하기 때문에 JPEG 및 애니메이션이 아닌 GIF 디코딩도 지원하지만 tf.image.decode_image
사용하는 것이 더 깔끔합니다.
인수:
- 범위: 범위 개체
- 내용: 0-D. PNG로 인코딩된 이미지입니다.
선택적 속성( Attrs
참조):
- 채널: 디코딩된 이미지의 색상 채널 수입니다.
