Aspects of the present invention relate to the technical field of face recognition, in particular to a method and device for judging a face shape. The step of obtaining the face image is to obtain the face image; the step of obtaining the key points of the face is to obtain the key points of the face based on the face image; the step of obtaining the comparison parameters is to obtain the comparison parameters based on the key points of the face. The comparison parameters include: face The length of the line segment between the key points, the angle between the line segments and the eccentricity of the face contour fitting ellipse; the step of obtaining the judgment parameter interval, obtaining the judgment parameter interval, the judgment parameter interval corresponds to the comparison parameter, and is used to judge the face shape; The matching step is to match the comparison parameter with the judgment parameter interval; the judgment step is to judge the face shape according to the result of the matching step. Through the above technical solution, the construction of the human face shape judgment model requires a small project, and the human face shape can be quickly recognized, thereby improving user experience.
Description
technical field [0001] The present invention generally relates to the technical field of face recognition, in particular to a method and device for judging a face shape. Background technique [0002] With the improvement of people's material standard of living, people's demand for personal image design is growing rapidly. Because of the development of science and technology and the improvement of technology industrialization application level, the corresponding service industries, such as image design, beauty salon, clothing jewelry, Make-up entertainment, etc. are also developing in the direction of personalization, specialization, science and informationization. By judging the face shape of a person, it helps people find products that suit them. [0003] In addition, in user terminal products such as mobile phones, there are also a large number of software or applications, such as face unlocking, face reshaping, 3D beautification, etc., which also need to detect and judge...
