Instance Attribute Summary

• #anger_likelihood ⇒ Google::Cloud::Vision::V1::Likelihood

  Anger likelihood.

• #blurred_likelihood ⇒ Google::Cloud::Vision::V1::Likelihood

  Blurred likelihood.

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

  The bounding polygon around the face.

• #detection_confidence ⇒ Float

  Detection confidence.

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

  The +fd_bounding_poly+ bounding polygon is tighter than the +boundingPoly+, and encloses only the skin part of the face.

• #headwear_likelihood ⇒ Google::Cloud::Vision::V1::Likelihood

  Headwear likelihood.

• #joy_likelihood ⇒ Google::Cloud::Vision::V1::Likelihood

  Joy likelihood.

• #landmarking_confidence ⇒ Float

  Face landmarking confidence.

• #landmarks ⇒ Array<Google::Cloud::Vision::V1::FaceAnnotation::Landmark>

  Detected face landmarks.

• #pan_angle ⇒ Float

  Yaw angle, which indicates the leftward/rightward angle that the face is pointing relative to the vertical plane perpendicular to the image.

• #roll_angle ⇒ Float

  Roll angle, which indicates the amount of clockwise/anti-clockwise rotation of the face relative to the image vertical about the axis perpendicular to the face.

• #sorrow_likelihood ⇒ Google::Cloud::Vision::V1::Likelihood

  Sorrow likelihood.

• #surprise_likelihood ⇒ Google::Cloud::Vision::V1::Likelihood

  Surprise likelihood.

• #tilt_angle ⇒ Float

  Pitch angle, which indicates the upwards/downwards angle that the face is pointing relative to the image's horizontal plane.

• #under_exposed_likelihood ⇒ Google::Cloud::Vision::V1::Likelihood

  Under-exposed likelihood.
