+
+      - **Check face image quality**: Assess whether a portrait meets certain standards, for example, ICAO, Schengen visa, USA visa. To perform image quality check, use the `processParam.quality` field.
+
+      - **Evaluate face attributes**: Estimate the age range of a person; check whether the eyes are occluded, closed, or open; detect a facial expression or smile; see if there are glasses, sunglasses, head coverage, medical mask, etc. To evaluate attributes, add the `processParam.attributes` field.

+      - By adding parameters manually. In this case, the configuration is not saved and can not be automatically repeated.
