hello.fiftyone.coco_utils module

hello.fiftyone.coco_utils.close_contour(contour)[source]
hello.fiftyone.coco_utils.coco_segmentation_to_mask(segmentation, bbox, frame_size)[source]

Returns a COCO segmentation mask.(patch)

Parameters:

  • segmentation – segmentation mask for the object.

  • bbox – a bounding box for the object in [xmin, ymin, width, height] format.

  • frame_size – the (width, height) of the image.

hello.fiftyone.coco_utils.get_mask_from_patch(mask, bbox, frame_size)[source]

Returns a COCO segmentation mask.(whole)

Parameters:

  • mask – an boolean numpy array defining the object mask

  • bbox – a bounding box for the object in [xmin, ymin, width, height] format

  • frame_size – the (width, height) of the image

hello.fiftyone.coco_utils.mask_to_coco_segmentation(mask, bbox, frame_size, mask_type='polygons', tolerance=1)[source]

Returns a RLE object.

Parameters:

  • mask – an boolean numpy array defining the object mask

  • bbox – a bounding box for the object in [xmin, ymin, width, height] format

  • frame_size – the (width, height) of the image
