The method further includes determining whether the person is wearing glasses, based on the face image. The method also includes determining whether the number of reflection points of light in a glasses region of the face image is four or more at the time of detecting the glasses region. The method also includes aligning the reflection points of light in order of size, upon determining that the number of reflection points of light is four or more. The method also includes detecting two virtual images of the light, based on the aligning. The method also includes detecting a face direction vector based on the two virtual images of the light."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for detecting face direction of a person","description":"A method for detecting face direction of a person includes receiving a face image of the person.
