example 1

[0097] Example 1 describes in detail how to replace a predetermined rigid body A image in one video stream with another predetermined rigid body B image. The application scenarios of the replacement processing are very wide. For example, during the live broadcast of a football game, the advertisement exhibit A in the arena is replaced with another advertisement exhibit B, so as to meet the needs of different people in different countries for advertisement display.

[0098] figure 2 is the flow chart of the video stream processing method according to the first example of the present invention, such as figure 2 shown, including the following steps.

[0099] Step S202, in a simple environment such as a solid color environment, extract the reference feature value group Ac and the reference contour A1 of the rigid body A. Wherein, each reference feature value group Ac may include four reference feature values, that is, the coordinates of the upper vertex, the lower vertex, the ...

example 2

[0131] Example 2 describes in detail how to replace a predetermined rigid body A image in one video stream with another predetermined rigid body B image. Compared with example 1, example 2 adopts a more cost-effective method in the process of determining the target contour of rigid body A, and increases the spatial attitude value group and attitude matching value during the replacement process of rigid body A and rigid body B.

[0132] image 3 is the flow chart of the video stream processing method according to the second example of the present invention, such as image 3 shown, including the following steps.

[0133] Step S302, in a simple environment such as a solid color environment, extract the reference feature value group Ac and the reference contour A1 of the rigid body A. Wherein, each reference feature value group Ac may include four reference feature values, that is, the coordinates of the upper vertex, the lower vertex, the left vertex and the right vertex of the...

Abstract

The invention discloses a video stream processing method and device. The method comprises the following steps: determining a target contour of a preset rigid body in an image frame in a video stream, and processing an image of the preset rigid body in the target contour, wherein the step of determining the target contour of the preset rigid body in the image frame in the video stream comprises the steps of determining a first upper vertex, a first lower vertex, a first left vertex and a first right vertex of the preset rigid body in the image frame, and matching a predetermined reference feature value set of the preset rigid body according to the first upper vertex, the first lower vertex, the first left vertex and the first right vertex, and determining a target contour of the preset rigid body in the image frame according to the matching result and a predetermined reference contour set of the preset rigid body. According to the invention, the contour of the preset rigid body in the video stream can be accurately determined in real time.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a video stream processing method and device. Background technique [0002] Video streaming generally refers to the continuous and stable transmission of video data over a network. Because the video stream is fluid, before the complete video data is transmitted, the video playback plug-in or browser on the computer can play it online, thereby improving user experience. [0003] The difference between a video stream and a specific video segment is that the specific video segment does not require real-time online playback, so that there is sufficient time for specific corrections or processing, or even manually. For a preset rigid body in a specific video segment, the usual processing methods are: (1) dividing the video segment into multiple image frames, (2) converting each image frame into a grayscale image and graying it according to the grayscale value Gradient processing, (3)...
