Represents a 2d single-instance binary segmentation mask.
Method generated by attrs for class Mask.
- as_class_mask(label_id: int | None = None, ignore_index: int = 0, dtype: dtype | None = None) ndarray [source]#
Produces a class index mask based on the binary mask.
- Parameters:
label_id – Scalar value to represent the class index of the mask. If not specified, self.label will be used. Defaults to None.
ignore_index – Scalar value to fill in the zeros in the binary mask. Defaults to 0.
dtype – Data type for the resulting mask. If not specified, it will be inferred from the provided label_id to hold its value. For example, if label_id=255, the inferred dtype will be np.uint8. Defaults to None.
- Returns:
Class index mask generated from the binary mask.
- Return type:
IndexMaskImage
- as_instance_mask(instance_id: int, ignore_index: int = 0, dtype: dtype | None = None) ndarray [source]#
Produces an instance index mask based on the binary mask.
- Parameters:
instance_id – Scalar value to represent the instance id.
ignore_index – Scalar value to fill in the zeros in the binary mask. Defaults to 0.
dtype – Data type for the resulting mask. If not specified, it will be inferred from the provided label_id to hold its value. For example, if label_id=255, the inferred dtype will be np.uint8. Defaults to None.
- Returns:
Instance index mask generated from the binary mask.
- Return type:

- property length: int | None#
Returns frame count of the closed interval [start_frame, end_frame], if video provides such information.
Note that not all videos provide length / duration metainfo, so the result may be undefined.
Also note, that information may be inaccurate because of variable FPS in video or incorrect metainfo. The count is only guaranteed to be valid after video is completely read once.
The count is affected by the frame filtering options of the object, i.e. start frame, end frame and frame step.
