Embodiment Construction

[0030] like figure 1 As shown, it is a flow chart of the screen saver method based on face authentication according to the embodiment of the present invention:

[0031] On the one hand, stored existing screensavers are normally executed by the computer, such as:

[0032] Step 107: Play the existing background video file.

[0033] Step 108: Perform audio decoding and video decoding on the video file.

[0034] The decoded audio can be output by an audio device. Videos can be combined as images captured by the camera.

[0035] on the other hand:

[0036] Step 101: First, a video image is captured by a video capture device (such as a camera).

[0037] Step 102: Combining with the face model library, face tracking recognition and authentication are performed on the basis of the captured images.

[0038] Step 103: Convert the captured video image into RGB24 format.

[0039] The original video image captured by the video capture device is generally in RGB or YUV2 format. If i...

Abstract

The present invention discloses a screen protection method based on human face authentication and its equipment. Said method includes the following steps: (1), playing back background video file as background of current screen protection image; (2), separating video image trapped by video trapping equipment into several video flows; (3), making the described several video flows and described background video undergo the process of synthesis and making display; and (4), making human face identification in video image trapped by described video trapping equipment, comparing the identified human face with basic model stored in data base and making authentication, when said authentication meets condition, unlocking and making screen protection.

Description

technical field [0001] The invention relates to a screen protection method and device, in particular to a screen protection method and device based on face authentication. Background technique [0002] For the screen saver method, the method that is often used is to play the screen saver image through program control, and the current screen saver is generally made for video, and the application of capturing video for synthetic video capture equipment (such as a camera) is seldom. [0003] With the wide application of network video technology, more and more people start to use video capture devices such as cameras to carry out activities such as chatting on the Internet, and at the same time, the number of applications for video capture devices is also increasing. [0004] On the other hand, as the needs of the online chat function, the image captured by the camera is usually the user's face, and face recognition technology is also a focus of current research in the computer ...
