Embodiment 1

[0041] see Figure 4 , the embodiment of the present invention provides a kind of face shape matching method, comprising:

[0042] 101. Obtain a sample of the image to be tested;

[0043] In this embodiment, the sample to be tested includes a face image, which may be a picture or a video stream, which is not specifically limited in this embodiment.

[0044] 102. Perform face detection on the sample of the image to obtain the shape feature of the face;

[0045] 103. Match the shape features of the human face with the shape features of all template images in the template image database one by one to obtain a template image most similar to the human face.

[0046] In another embodiment, before acquiring the sample of the image to be tested, it also includes:

[0047] A template image database is established, and the template image database includes shape features of the template image.

[0048] In another embodiment, the establishment of the template image database includes: ...

Embodiment 2

[0070] The embodiment of the present invention provides a matching method of human face shape, see Figure 5 , the method flow includes:

[0071] 201. Obtain object images of different shapes, and intercept the main part of each object image to obtain a normalized template image.

[0072] In this embodiment, a template image database of objects of different shapes is established, and the object in the database whose shape is most similar to a human face is retrieved for any human face. According to the change of shape, there are many types of template images, such as animals, food, furniture, plants, etc., but in order to make the face matching effect better, in this embodiment, there are mainly two types: pets and food. The pet category includes different kinds of pets, such as cats, dogs, mice, etc., and the food category includes pictures of real objects in daily life, such as melon seeds, duck eggs, etc. However, the specific execution process is not limited to these two...

Embodiment 3

[0112] see Figure 8 , the embodiment of the present invention provides a face shape matching system, including: a test sample acquisition module 301 , a face shape extraction module 302 and a face shape matching module 303 .

[0113] A test sample acquisition module 301, configured to acquire a sample of an image to be tested;

[0114] The face shape extraction module 302 is used to perform face detection on the sample of the image to obtain the shape feature of the face;

[0115] The human face shape matching module 303 is configured to match the shape features of the human face with the shape features of all the template images in the template image database one by one to obtain the template image most similar to the human face.

[0116] see Figure 9 , in another embodiment, the system also includes:

[0117] The template image database building module 304 is used to create a template image database before the test sample acquisition module acquires samples of images to...

Abstract

Systems for matching face shapes may include a computer-readable non-transitory storage medium and an executing hardware unit. The storage medium may include a set of instructions for target object shape matching. The executing hardware unit may be in communication with the storage medium and may be configured to execute the set of instructions. The executing hardware unit may be configured to obtain a target object image for shape matching; determine a shape character of the target object image based on a shape of the target object image; determine similarities between the target object image and a plurality of template images of reference objects based on the shape character of the target object image and shape characters of the reference objects in the plurality of template images; and select a template image from the plurality of template images that has a largest similarity to the target object image.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a face shape matching method and system. Background technique [0002] With the advancement of computer technology, face recognition technology is becoming more and more mature. The current face recognition specifically refers to computer technology that uses analysis and comparison of face visual feature information for identity identification. Shape is one of the most direct ways of expressing an object. Objects of similar shape abound in daily life, and human faces are often compared with other objects for description. For example, describe a human face as an oval face, oval face, and someone's face is similar to a certain pet dog, etc. Describing human faces with specific objects can not only increase the interest, but also make the appearance of human faces deeper. [0003] Therefore, the simple way of identifying the face in the prior art can no longer meet the...
