#bounding_poly ⇒ Google::Cloud::Vision::V1::BoundingPoly

Returns The bounding polygon around the face. The coordinates of the bounding box are in the original image's scale, as returned in ImageParams. The bounding box is computed to "frame" the face in accordance with human expectations. It is based on the landmarker results. Note that one or more x and/or y coordinates may not be generated in the BoundingPoly (the polygon will be unbounded) if only a partial face appears in the image to be annotated.

Returns:

#fd_bounding_poly ⇒ Google::Cloud::Vision::V1::BoundingPoly

Returns This bounding polygon is tighter than the previous boundingPoly, and encloses only the skin part of the face. Typically, it is used to eliminate the face from any image analysis that detects the "amount of skin" visible in an image. It is not based on the landmarker results, only on the initial face detection, hence the fd (face detection) prefix.

Returns:
