Example Embodiment

[0016] When implementing the present invention, the applicant found that when performing lip state detection, the detection can be performed through changes in the received voice data or additional external sensors such as infrared sensors. However, these methods require additional equipment or sensors and cannot pass The pure visual information of the image is used to detect the lip status.

[0017] The embodiment of the present invention provides a method and device for detecting lip status, which can effectively detect the status of the lip region, has high recognition accuracy and low cost, and can effectively remove the influence of noise data such as silent frames on the lip recognition result and reduce Interference, improve data processing efficiency.

[0018] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the p...

Abstract

The embodiment of the invention provides a method and a device for detecting the lip state. The method comprises the steps of performing lip region detection on a target image to obtain a lip region image comprising the target image; determining a plurality of key characteristic points in the lip region image; according to characteristic values corresponding to the key characteristic points, determining the state of the lip region, wherein the state of the lip region can be an opened state or a closed state. According to the embodiment of the invention, the state of the lip region can be effectively detected, wherein the recognition accuracy is high and the cost is low. Meanwhile, the influences of noise data, such as a mute frame and the like, on the lip language recognition result can beeffectively removed. The interference is reduced, and the data processing efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular to a lip state detection method and device. Background technique [0002] With the development of artificial intelligence technology, voice interaction has become a widely used technology. However, since voice interaction is easily affected by the environment, it is prone to noise interference, resulting in inaccurate voice recognition results. In order to improve the problem of inaccurate speech recognition, lip recognition technology has emerged. Lip language recognition technology is a technology that recognizes facial images to obtain corresponding language recognition results. In order to reduce the impact of noise data, the current lip language recognition technology usually starts to collect video images when a voice signal is received; when the voice signal ends, it stops collecting video images. This method avoids the influence of noise data t...
