Embodiment 1

[0018] refer to figure 1 , which shows a flow chart of the steps of an image-based control method provided in Embodiment 1 of the present invention, which may specifically include the following steps:

[0019] Step 102, extract facial feature points from video image data.

[0020] The embodiment of the present invention can be applied to video chatting of social software or video calling of mobile terminals, for example, using QQ, WeChat and other software for video chatting, and for example, using smart phones for video calling.

[0021] In the embodiment of the present invention, in order to protect the personal privacy of the user and improve the interest of the video, the video image data collected by the terminal from the camera is processed. After receiving the video image data, the terminal analyzes the multiple video image frames to determine the user's facial feature points in the video image frames.

[0022] It should be noted that, in the embodiment of the present...

Embodiment 2

[0031] refer to figure 2 , which shows a flow chart of the steps of an image-based control method provided in Embodiment 2 of the present invention, which may specifically include the following steps:

[0032] Step 202 , judging whether the receiving object of the video meets the preset condition, if yes, then execute step 204 , otherwise end this process.

[0033] In the embodiment of the present invention, in order to protect the personal privacy of the user and improve the interest of the video, the facial movements of the current user are displayed in the frame of the video object with a virtual three-dimensional facial model.

[0034] In actual use, certain preset conditions can be set, that is, the conditions for enabling the virtual video mode are met. The preset conditions can include but are not limited to: the scope of the set contacts, such as contacts not in the address book, or , the contacts set by the user.

[0035] When the user conducts video communication,...

Embodiment 3

[0058] refer to Figure 4 , which shows a structural block diagram of an image-based control device provided in Embodiment 3 of the present invention; specifically, the following modules may be included:

[0059] The extraction module 402 is used for extracting facial feature points from video image data.

[0060] The detection module 404 is configured to detect the position change of the extracted facial feature points.

[0061] The control module 406 is configured to control the change of facial movements of the corresponding facial three-dimensional model according to the position changes of the facial feature points.

[0062] The embodiment of the present invention extracts facial feature points from video image data, detects the position changes of the extracted facial feature points, and controls the facial action changes of the corresponding facial three-dimensional model according to the position changes of the facial feature points. The embodiment of the present inv...

Abstract

The embodiment of the invention discloses an image-based control method and an image-based control device, and relates to the technical field of digital image processing. The method comprises the following steps: extracting a face feature point from video image data; detecting a position change of the extracted face feature point; and controlling face action changes of a corresponding face three-dimensional model according to the position change of the extracted face feature point. According to the image-based control method and the image-based control device, the face action of a user can be virtually and vividly described through the face three-dimensional model; and furthermore, the privacy of the user can be protected, and the interestingness of a video can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of digital image processing, and in particular, to an image-based control method and device. Background technique [0002] With the development of science and technology, real-time communication between users is not limited to voice communication through telephone, users can also perform real-time video communication through terminal equipment, such as video calls. [0003] In the prior art, when real-time video communication is adopted, the video images of both parties in the dialogue are generally real images of the user. But sometimes although the user carries out video chat with the other side, but hopes to keep certain privacy, does not hope that the other side sees own real video. [0004] During the process of implementing the embodiments of the present invention, the inventors found that the prior art has at least the following defects: in the existing real-time video communica...
