tumourkit.utils.preprocessing.apply_mask

tumourkit.utils.preprocessing.apply_mask(img: ndarray, mask: ndarray) → Tuple[ndarray, int, int]

Apply a binary mask to an RGB image.

Parameters:

• img (np.ndarray) – RGB image.

• mask (np.ndarray) – Binary mask.

Returns:

Tuple containing the masked image, the bounded box mask, the center of the mask in the masked image.

Return type:

Tuple[np.ndarray, np.ndarray, int, int]

For efficiency only the bounded box of the mask is returned, together with the center of the box. Coordinates are indices of array.
