class SuperPointConfig(PreTrainedConfig):

    encoder_hidden_sizes (`List`, *optional*, defaults to `[64, 64, 128, 128]`):
        The number of channels in each convolutional layer in the encoder.
    keypoint_decoder_dim (`int`, *optional*, defaults to 65):
        The output dimension of the keypoint decoder.
    descriptor_decoder_dim (`int`, *optional*, defaults to 256):
        The output dimension of the descriptor decoder.
    keypoint_threshold (`float`, *optional*, defaults to 0.005):
        The threshold to use for extracting keypoints.
    max_keypoints (`int`, *optional*, defaults to -1):
        The maximum number of keypoints to extract. If `-1`, will extract all keypoints.
    nms_radius (`int`, *optional*, defaults to 4):
        The radius for non-maximum suppression.
    border_removal_distance (`int`, *optional*, defaults to 4):
        The distance from the border to remove keypoints.

    Example:
    ```python
    >>> from transformers import SuperPointConfig, SuperPointForKeypointDetection

    >>> # Initializing a SuperPoint superpoint style configuration
    >>> configuration = SuperPointConfig()
    >>> # Initializing a model from the superpoint style configuration
    >>> model = SuperPointForKeypointDetection(configuration)
    >>> # Accessing the model configuration
    >>> configuration = model.config
