Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] According to an embodiment of the present invention, a mouth-breathing face recognition method is provided. Such as figure 1 Shown is a flow chart of a mouth-breathing face recognition method according to an embodiment of the present invention.

[0034] Step S110, collecting valid face images.

[0035] A valid human face image refers to an image containing a human face and having an average brightness value within a preset average brightness value range.

[0036] Step S120, determining the pose angle of the target face in the effective face image.

[0037] The target face refers to the face of the user whose mouth-breathing face is to be recognized.

[0038] The pose angles (θ, ψ, φ) of the target face include: pitch angle θ, y...

Abstract

The invention discloses a mouth-breathing face recognition method, device and storage medium. The method includes: collecting an effective face image; determining the attitude angle of the target face in the effective face image; if the attitude angle of the target face is within the preset attitude angle range, extracting the target face from the effective face image Structural metric features of the face; input the structural metric features of the target face into the pre-trained mouth-breathing face recognition model, and obtain the mouth-breathing face recognition result output by the mouth-breathing face recognition model; wherein, image processing is carried out on the preset positive sample image Augmentation processing, using the positive sample image after image augmentation processing and the preset negative sample image to train the mouth-breathing face recognition model. The invention uses image processing technology combined with a pre-trained mouth-breathing face recognition model to identify whether a target face is a mouth-breathing face, and solves the problem of high cost for both suspected patients and doctors in the mouth-breathing face diagnosis process.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a mouth-breathing face recognition method, device and storage medium. Background technique [0002] Mouth-breathing face is also called "adenoid face" clinically. Mouth-breathing facial appearance is a specific dental and maxillofacial deformity formed due to changes in the developing teeth and jaws caused by adenoid hypertrophy. This deformity reflects on the human face and causes a different appearance from ordinary people. People with hypertrophic adenoids tend to typically use oral rather than nasal breathing habits, and it is this breathing habit that causes the facial features of this group of people, usually flat nose, short lips, receding chin, head Forward leaning and other characteristics. [0003] People with mouth-breathing faces are often accompanied by some sleep problems, such as: difficulty falling asleep at night, severe snoring, etc., and mout...
