decode_image

torchvision.io.decode_image(input: torch.Tensor, mode: torchvision.io.image.ImageReadMode = <ImageReadMode.UNCHANGED: 0>) → torch.Tensor

Detects whether an image is a JPEG or PNG and performs the appropriate operation to decode the image into a 3 dimensional RGB or grayscale Tensor.

Optionally converts the image to the desired format. The values of the output tensor are uint8 in [0, 255].

Parameters

• input (Tensor) – a one dimensional uint8 tensor containing the raw bytes of the PNG or JPEG image.

• mode (ImageReadMode) – the read mode used for optionally converting the image. Default: ImageReadMode.UNCHANGED. See ImageReadMode class for more information on various available modes.

Returns

output (Tensor[image_channels, image_height, image_width])
