Embodiment 1

[0025] refer to figure 1 , shows a flowchart of steps of a tooth beautification method provided by an embodiment of the present invention. Applied to a mobile terminal, the method includes:

[0026] Step 101, acquiring a face image.

[0027] In this embodiment, the mobile terminal may use a camera to collect face images, or obtain face images from a local photo album or a remote server. This embodiment of the present invention does not limit it in detail, and it can be set according to actual conditions.

[0028] Step 102, determine the tooth area in the face image, and locate the abnormal tooth area and the normal tooth area from the tooth area according to the depth information corresponding to the tooth area.

[0029] In this embodiment, the face image is recognized according to the characteristics of the tooth area, and the tooth area is determined. And according to the difference between normal teeth and abnormal teeth, the normal tooth area and abnormal tooth area ar...

Embodiment 2

[0036] refer to figure 2 , shows a flowchart of steps of a tooth beautification method provided by an embodiment of the present invention. Applied to a mobile terminal, the method includes:

[0037] Step 201, acquiring a face image.

[0038] Step 202, determining a mouth area in the face image.

[0039] In this embodiment, the mouth feature points are extracted from the face image, and the largest circumscribed rectangle of the mouth feature points is used as the mouth area. In this way, the processing area can not only be limited to the vicinity of the human mouth, the information interference of other images can be eliminated, the recognition accuracy of the teeth can be improved, and the processing time of the algorithm can also be saved.

[0040] Step 203 , when it is determined that the human mouth is in an open state, a preset thresholding algorithm is used to perform thresholding processing on the human mouth area to obtain a thresholded image.

[0041] In this emb...

Embodiment 3

[0064] refer to image 3 , shows a structural block diagram of a tooth beautification device provided by an embodiment of the present invention. Deployed on a mobile terminal, the device includes a face image acquisition module 301, a tooth area determination module 302, a tooth restoration module 303, and a tooth beautification module 304:

[0065] Facial image acquisition module 301, used to acquire facial images;

[0066] A tooth area determining module 302, configured to determine a tooth area in the face image, and locate an abnormal tooth area and a normal tooth area from the tooth area according to the depth information corresponding to the tooth area;

[0067] Tooth restoration module 303, configured to repair the abnormal tooth region according to the normal tooth region;

[0068] The tooth beautification module 304 is configured to perform beautification processing on the tooth area.

[0069] exist image 3 Optionally, the tooth region determination module 302 in...

Abstract

A method and apparatus for beautifying teeth are provided, and are applied to a terminal. The method comprises the following steps: acquiring a face image; determining a tooth region in the face image, and positioning an abnormal tooth region and a normal tooth region from the tooth region according to depth information corresponding to the tooth region; performing repair processing on the abnormal tooth region according to the normal tooth region; and beautifying the tooth area. Through the embodiment of the invention, not only are the teeth whitened, but also the treatment of self-adaptive tooth repair and the like can be realized, the user with defective teeth can open his mouth at will when taking photos, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a tooth beautification method and device. Background technique [0002] Nowadays, smart mobile terminals are becoming more and more popular, and more and more users use smart mobile terminals for shooting, especially portrait photography. The beautification mode is usually turned on when taking portraits. The current beautification algorithm mainly studies facial skin smoothing and facial features adjustment. There are relatively few beauty algorithms for teeth, and usually only whiten teeth. Contents of the invention [0003] Embodiments of the present invention provide a tooth beautification method and device to solve the problem in the prior art that the beautification algorithm only whitens the teeth. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a tooth beautification method, which is applied to a mobile...
