deltacamera.reproject_mask(mask, old_camera, new_camera, dst_shape, border_mode=cv2.BORDER_CONSTANT, border_value=0, interp=None, antialias_factor=1, dst=None, return_validity_mask=False)[source]#

Reproject a binary mask from one camera view to another.

Parameters:

  • mask – Binary mask array (bool or uint8) in the old camera’s image space.

  • old_camera – Source camera.

  • new_camera – Target camera.

  • dst_shape – Output shape (height, width).

  • border_mode – OpenCV border mode for out-of-bounds pixels.

  • border_value – Value for border pixels.

  • interp – Interpolation method.

  • antialias_factor – Antialiasing factor (1 = no antialiasing).

  • dst – Optional pre-allocated output array.

  • return_validity_mask – If True, also return a mask of valid pixels.

Returns:

Reprojected mask, or tuple of (mask, validity_mask) if return_validity_mask=True.
