AI Technical Summary

Problems solved by technology

Artificial enhancement is mainly through the use of professional software by professional technicians to optimize and enhance frame by frame, which requires a lot of manpower and time costs
Algorithm enhancement is mainly for single-frame image enhancement, that is, to enhance the video frame by frame, which will lead to inconsistent enhancement effects between frames, resulting in sudden changes in the color of the output video image or mutual bright and dark brightness, etc.

Embodiment Construction

[0073] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0074] figure 1 is a flow chart of the steps of a video processing method provided by an embodiment of the present invention, and the method can be applied to a server, such as figure 1 As shown, the method may include:

[0075] Step 101, segmenting the video to be processed into segments to obtain at least one video segment.

[0076] Due to the existence of clips in the video, there are often scene switching, and the main color of each scene...

Abstract

The present invention provides a video processing method, device, server and storage medium, the method comprising: segmenting the video to be processed to obtain at least one video segment; for each video segment, according to the specified frame in the video segment, obtaining The color adjustment parameter of the specified frame is used as the color adjustment parameter corresponding to the video paragraph; for each video paragraph, according to the color adjustment parameter corresponding to the video paragraph, each frame in the video paragraph is color enhanced to obtain target video. Since each frame in a video segment adopts the same color adjustment parameters for enhancement processing, the present invention avoids problems such as color mutation of the picture or mutual brightening and darkening of brightness, ensures consistent enhancement effect between frames, and does not require manual processing Color Enhancement, which improves the efficiency of color enhancement.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video processing method, device, server and storage medium. Background technique [0002] With the rapid development of Internet technology, users can not only browse videos on the Internet, but also shoot videos by themselves and upload and share them, that is, UGC (User Generated Content, User Generated Content) appears. [0003] There are a large number of videos uploaded by users on the Internet UGC every day. However, due to the large difference in the quality of users’ shooting equipment, most of the uploaded videos will have some problems, such as dim images due to insufficient lighting, and over-exposed images. Exposure, overbrightness, low contrast and low saturation of the video content caused by old equipment or old film sources, unnatural image color and image distortion caused by incorrectly setting camera parameters. At present, the above problem...
