Embodiment 1

[0179] The embodiment of the present invention provides a kind of face beautification method in real-time video, refer to figure 1 As shown, the method flow includes:

[0180] 101. The sender acquires the current real-time video frame, and generates an importance matrix of the current real-time video frame according to the current real-time video frame.

[0181] Specifically, generating the importance matrix of the current instant video frame includes:

[0182] Divide the current instant video frame into N multiplied by N macroblocks;

[0183] Obtain the number of pixels marked as important in each macroblock;

[0184] Generate an importance matrix of the current instant video frame according to the number of important pixels in each macroblock;

[0185] Wherein, the greater the number of marked important pixels in each macroblock, the more important the corresponding macroblock is.

[0186] Optionally, obtaining the number of marked important pixels in each macroblock inc...

Embodiment 2

[0214] The embodiment of the present invention provides a face beautification method in the instant video, in the embodiment of the present invention, the executing subject of the method is the sender of the instant video in the instant video process, refer to figure 2 As shown, the method flow includes:

[0215] 201. The sender acquires the current real-time video frame.

[0216] Wherein, the sender includes the electronic device of the sender.

[0217] Specifically, the sending-side electronic device can acquire the current video frame through the camera according to the preset video frame acquisition instruction, and the embodiment of the present invention does not limit the specific acquisition instruction and acquisition method.

[0218] 202. Generate an importance matrix of the current instant video frame according to the current instant video frame.

[0219] Specifically, the process of generating the importance matrix of the current instant video frame may include: ...

Embodiment 3

[0300] The embodiment of the present invention provides a face beautification method in instant video, in the embodiment of the present invention, the subject of execution of the method is the receiver of the instant video in the instant video process, refer to image 3 As shown, the method flow includes:

[0301] 301. The receiver receives the encoded current instant video frame and brightness and / or chroma adjustment parameters from the sender.

[0302] The embodiment of the present invention does not limit the specific display manner.

[0303] 302. The receiver decodes the encoded current instant video frame.

[0304] Specifically, the receiver performs decoding according to the quantization parameter corresponding to each macroblock of the current instant video frame.

[0305] 303. The receiver adjusts the brightness and / or hue of the decoded current instant video frame according to the brightness and / or hue adjustment parameters.

[0306] Specifically, the receiver use...

Abstract

The invention discloses a face beautification method and system in an instant video and a device and belongs to the field of image processing. The method comprises the steps that a sender smoothes a current instant video frame and codes the smoothed current instant video frame according to an importance matrix; the sender obtains a brightness and / or chrominance adjustment parameter of the current instant video frame; the coded current instant video frame and the brightness and / or chrominance adjustment parameter are sent to a receiver; the receiver decodes the coded current instant video frame; and the receiver carries out brightness and / or chrominance adjustment on the decoded current instant video frame according to the brightness and / or chrominance adjustment parameter. The smoothed current instant video frame is coded according to the importance matrix, the calculation efficiency is improved, and moreover, the receiver carries out the brightness and / or chrominance adjustment on the decoded current instant video frame, thereby facilitating solution of the problem that a code rate is increased due to the fact that the video frame is smoothed and the brightness and / or chrominance adjustment is carried out at the same.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a face beautification method, device and system in real-time video. Background technique [0002] Now, with the popularization of instant video applications on mobile terminals and the improvement of people's aesthetics, more and more users use instant video applications to interact with others, and users are more willing to use facial recognition during the interaction process. Beautified video images for interaction. [0003] Face beautification generally includes skin smoothing and brightness adjustment. In the prior art, the sender in the video interaction process obtains real-time video frames and performs smoothing and brightness adjustment on the video, and the smoothed and brightness-adjusted The real-time video frame is encoded, and the encoded real-time video frame is sent to the receiver, and the receiver decodes and displays the video frame. [0004] When using the m...
