no. 1 example

[0027] refer to figure 1 , showing a flowchart of an image processing method according to an embodiment of the present invention, which is applied to a mobile terminal, and the method may specifically include the following steps:

[0028] Step 101, identifying the hair region included in the face region in the target image and the skin region adjacent to the hair region;

[0029] Wherein, the target image is an image to be recognized, and the target image includes a person, and the person has a face, hair, and the like. This step is mainly to identify an initial hairline region from the face region (including the hair region) of the target image, and the initial hairline region includes the hair region and the skin region adjacent to the hair region.

[0030] Wherein, the target image may be a two-dimensional image or a three-dimensional image.

[0031] Of course, the boundaries of the hair region and the skin region identified here are not necessarily real boundaries. There...

[0046] refer to figure 2 , showing a flow chart of an image processing method according to another embodiment of the present invention, which is applied to a mobile terminal, and may specifically include the following steps:

[0047] Step 201, identifying the position information and angle information of the face area in the target image;

[0048] Wherein, the position of the face area in the target image can be identified, and in addition, the three-dimensional angle of the face area can be identified (for example, the head is lowered by 30 degrees, or the head is raised by 30 degrees, etc.).

[0049] Step 202, according to the position information and the angle information, identify the hair area included in the face area in the target image and the skin area adjacent to the hair area;

[0050] That is, according to the position information and the angle information, the initial hairline area (consisting of the above-mentioned hair area and the above-mentioned adjacent skin ...

[0083] refer to image 3 , showing a flowchart of an image processing method according to another embodiment of the present invention, which is applied to a mobile terminal, and may specifically include the following steps:

[0084] Step 301, identifying the hair region included in the face region in the target image and the skin region adjacent to the hair region;

[0085] For details, refer to step 101 of the first embodiment, which will not be repeated here.

[0086] Step 302, acquiring a depth image corresponding to the target image;

[0087] Wherein, the target image is a two-dimensional image, and there are many methods for obtaining a depth image corresponding to the two-dimensional image. Here are a few schematic examples to illustrate:

[0088] A three-dimensional (3D) camera can be used to shoot people, so that not only the target image can be obtained, but also the depth image corresponding to the target image can be obtained;

[0089] Alternatively, 3D modeling...

Abstract

The invention provides an image processing method and device and a mobile terminal. The method comprises the following steps: identifying a hair region included in a face region in a target image anda skin region adjacent to the hair region; Determining a hairline position according to the depth information of the hair region and the skin region; processing a human face region in the target imageaccording to the hairline position. The method recognizes a hair region and an adjacent skin region included in a face region in a target image, and identifies the hairline position according to thedepth information of the hair region and the skin region, Even if the ambient light is dim, the hairline position in the face region can be accurately recognized, so that the target image can be processed reasonably according to the hairline position, and the purpose of hairline beauty is achieved, so that the proportion of the face in the processed image is more coordinated.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device and mobile terminal. Background technique [0002] With the continuous development of Internet technology, the popularity of mobile terminals provides users with great convenience. For example, due to the portability of smart terminals, users use mobile phones instead of cameras to take pictures. [0003] In the process of taking pictures or processing images, you can perform beauty treatments such as face thinning, whitening, and eye enlargement on the image. However, it is difficult to accurately find the position of the hairline and perform beauty treatment on it. Contents of the invention [0004] Embodiments of the present invention provide an image processing method, device, and mobile terminal to solve the problem in the image processing method in the related art that it is difficult to accurately find the position of ...
