Embodiment 1

[0125] figure 1 It is a flowchart of an image processing method provided by Embodiment 1 of the present invention. This embodiment is applicable to a scene where blurring or brightening processing is performed on the original image data under the condition of protecting the outline of the human face. The method can be performed by an image processing device, which can be implemented by software and / or hardware, and can be configured in electronic devices, such as mobile phones, tablet computers, wearable devices (such as smart glasses, smart watch), etc., the electronic device is configured with a screen, a central processing unit (CPU), and a graphics processing unit (GPU). refer to figure 1 , the method specifically includes:

[0126] S101. Determine original image data.

[0127] The original image data refers to a collection of values ​​of each pixel (pixel) represented by a numerical value. Determining the original image data refers to processing the received image da...

Embodiment 2

[0147] Figure 2A It is a flow chart of an image processing method provided by Embodiment 2 of the present invention. This embodiment is refined on the basis of the first embodiment, and describes in detail the specific process of determining the contour points used to represent the contour of the human face from the pixel points according to the texture coordinates. refer to Figure 2A , the method includes:

[0148] S201. Receive original image data.

[0149] The method of acquiring image data may refer to capturing live images uploaded by anchor users through camera equipment, or receiving images input by users. Typically, raw image data includes people. That is, the original image data can be divided into a human body part and a background part.

[0150] Generally, the received original image data is in RGB color mode. Each pixel in the original image data has a texture coordinate, and the texture coordinate includes four parameters, which are respectively used to st...

Embodiment 3

[0280] image 3 It is a flow chart of a live broadcast method provided by Embodiment 3 of the present invention. This embodiment is applicable to the scenario of processing the video data uploaded by the anchor client to the live broadcast room. The method can be executed by a live broadcast device, especially a mobile phone, a computer, etc. used by a host client. The device can be realized by software and / or hardware. refer to image 3 , the method specifically includes:

[0281] S301. Collect original video data.

[0282] The original live video data includes original image data, and each pixel in the original image data has texture coordinates. It should be understood that since this embodiment is applicable to the scene where the host performs live broadcast, audio data should be collected while collecting original live video data.

[0283] In a feasible implementation, when the anchor user activates the live broadcast function in the live broadcast room, the live b...

Abstract

The invention discloses an image processing and live broadcast method, device, equipment and storage medium. The method includes: determining original image data, each pixel point in the original image data has texture coordinates; determining contour points used to represent the contour of a human face from the pixel points according to the texture coordinates; and retaining the contour Convert the blurred original image data into grayscale image data on the basis of dots; superimpose the grayscale image data and the original image data to obtain target image data. The method solves the problem of incomplete recognition of the skin area, uneven facial skin color caused by the microdermabrasion operation, and blurred facial contours caused by the microdermabrasion operation after expanding the range of the skin area.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular, to an image processing and live broadcast method, device, device, and storage medium. Background technique [0002] With the popularity of beautification, more and more users hope to beautify the characters in pictures or videos through beautifying tools. [0003] Especially in the field of mobile phone photography and live broadcast, the demand for beauty is becoming more and more prominent. Common beauty treatments include face-lifting, skin resurfacing, etc. Taking dermabrasion as an example, the method of identifying skin color is generally used to determine the skin, and after blurring the skin area, it is realized by superimposing the skin area back to the original image. [0004] However, the skin color recognition in the color space is very sensitive to light. At night, the skin area cannot be fully identified, and in the case of strong outdoor li...
