CREStereo

class torchvision.datasets.CREStereo(root: str, transforms: Optional[Callable] = None)

Synthetic dataset used in training the CREStereo architecture. Dataset details on the official paper repo.

The dataset is expected to have the following structure:

            img1_right.disp.jpg

Parameters:

• root (str) – Root directory of the dataset.

• transforms (callable, optional) – A function/transform that takes in a sample and returns a transformed version.

Special-members:

__getitem__(index: int) → Tuple[Image, Image, Optional[ndarray], ndarray]

Return example at given index.

Parameters:

index (int) – The index of the example to retrieve

Returns:

A 4-tuple with (img_left, img_right, disparity, valid_mask). The disparity is a numpy array of shape (1, H, W) and the images are PIL images. valid_mask is implicitly None if the transforms parameter does not generate a valid mask.

Return type:

tuple
