mmcv.image.ycbcr2bgr¶
- mmcv.image.ycbcr2bgr(img: numpy.ndarray) → numpy.ndarray[源代码]¶
Convert a YCbCr image to BGR image.
The bgr version of ycbcr2rgb. It implements the ITU-R BT.601 conversion for standard-definition television. See more details in https://en.wikipedia.org/wiki/YCbCr#ITU-R_BT.601_conversion.
It differs from a similar function in cv2.cvtColor: YCrCb <-> BGR. In OpenCV, it implements a JPEG conversion. See more details in https://en.wikipedia.org/wiki/YCbCr#JPEG_conversion.
- 参数
img (ndarray) – The input image. It accepts: 1. np.uint8 type with range [0, 255]; 2. np.float32 type with range [0, 1].
- 返回
The converted BGR image. The output image has the same type and range as input image.
