Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0029] In order to reduce the complexity of smile detection to meet the low-complexity requirements of mobile terminal hardware processing, and to apply smile detection to various mobile terminals with camera equipment, the inventor considers that since human lips contain relatively rich human faces Therefore, in the embodiment of the present invention, the smiling face is more accurately detected by tracking the movement information of the lips, so that the calculated information is less than that of a human face, and the calculation is relatively simple.

Abstract

The invention discloses a smiling detection method, comprising the following steps: capturing the motion information of the lip in the human face video image and determining whether the smiling face is detected according to the motion information of the lip. The invention also discloses a smiling face detection device and a mobile terminal. The adoption of the invention can achieve the purpose oflowering the complexity of smiling face detection, and the embodiment of the invention can be adapted to the requirements of low complexity of mobile terminal hardware processing, reduce the hardwarecost of the device; and the invention has wide application range and less limitation, and can be used for various mobile terminals with camera shooting devices.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a smile detection method and device, and a mobile terminal. Background technique [0002] With the rapid development of mobile terminals, users have higher and higher requirements for various functional modules of mobile terminals, and they are more eager to apply some functions of personal computers or digital products to mobile terminals; No exception, among them, the smile detection function, which is highly praised by the majority of users, also hopes to be applied on mobile terminals. [0003] But, in the process of realizing the present invention, the inventor finds that the prior art has the following deficiencies: [0004] The existing smile detection function algorithm is relatively complex, the calculation complexity is high, and the hardware conditions of the detection equipment are high, and some even require some special hardware equipment. Therefore, on some ...
