Functions

coco_to_binary_masks(ch, dest_dir[, scaling])	Converts annotations from COCO to binary masks.
compressed_rle_to_mask(rle_code[, height, ...])	Converts a compressed RLE to a binary mask with the given output dtype.
compute_polygon_area(polygon)	Computes a segmentation area from its polygon coordinates.
convert_to_mask(segmentation, height, width, ...)	Converts a segmentation to a binary mask.
convert_to_mode(segmentation, mode, height, ...)	Converts a segmentation to the specified mode.
decode_mask(code, mode, **kwargs)	Decodes a mask using the specified mode. :param code: the encoded mask. :param mode: the mode to use for decoding the mask. :param **kwargs: extra parameters such as: - height and width to indicate the shape of the output mask (if mode in [cRLE, polygon]). - value to indicate the value of the zero-valued pixels in the output mask (if mode=polygon). - dtype to indicate the type of the output mask (if mode in [RLE, cRLE, polygon]).
encode_mask(mask, mode, **kwargs)	Encodes a mask using the specified :param mask: a binary mask as a numpy array.
get_segmentation_mode(segmentation)	Automatically detect the segmentation format: RLE, cRLE or polygon.
mask_to_compressed_rle(mask, **kwargs)	Converts a binary mask to compressed RLE format.
mask_to_polygon(mask[, simplify_tolerance])	Converts segmentation mask to a list of polygons.
mask_to_rle(binary_mask, **kwargs)	Converts a binary mask to RLE encoding.
polygon_to_mask(polygon_code[, width, ...])	Creates and returns a mask from polygon in COCO format.
rle_to_mask(rle_code[, dtype])	Converts an RLE to a binary mask with the given output dtype.
