Embodiment Construction

[0037] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Such as figure 1 As shown, the embodiment of the present invention provides a method for adaptively clearing video images, including:

[0039] S1: Acquiring currently collected video images or pre-stored video images;

[0040] Specifically, the video image of the current scene can be collected by the camera for subsequent processing, or the pre-stored video image can be obtained from the local database.

[0041] S2: Divide the video image into color information and brightness information;

[0042] Specifically, the currently collected video images or the original files acquired locally are streamed, and the video files are divided into a color stream and a brightness stream.

[0043] S3: Estimate the acquisition scene of the video image according to the color information and brightness information;

[0044] Analyzing the above video stream and...

Abstract

The invention relates to a video picture adaptive clearing processing method and device, which includes: acquiring a currently collected video image or a pre-stored video image; dividing the video image into color information and brightness information; and estimating the video image according to the color information and brightness information. According to the estimated collection scene and the pre-stored video parameter standards corresponding to the scene, the video image is processed for clarity. Embodiments of the present invention provide technical solutions that can automatically identify the video shooting environment, brightness, color and other environmental information, use the principle of fuzzy control to judge whether these information are in the appropriate video parameter standard interval, and automatically select the corresponding video for the video that needs to be processed. The clearing algorithm is used to process the video, so that the video can be saved or displayed in a clearer way, which can satisfy the clearing process of video images in a variety of different scenes, and solves the existing defect of being able to clear only one scene.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method and device for adaptively clearing video images. Background technique [0002] With the rapid development of computer network and multimedia technology, the application of video is changing people's life and becoming an indispensable part of our life. At present, video technology has a wide range of applications, such as medical diagnosis, aerospace, industrial and agricultural production, meteorology, video surveillance and other fields. Video information is used by people to solve practical problems. [0003] In real life, due to the existence of various factors, the videos we obtain often cannot meet the needs of practical applications. For example, the video quality is low due to long-term copying, transmission, format conversion, display, etc. of the video. At the same time, due to the influence of lighting conditions, the contrast and color of t...
