Embodiment Construction
[0037] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0038] Such as figure 1 As shown, the embodiment of the present invention provides a method for adaptively clearing a video picture, including:
[0039] S1: Obtain the currently collected video image or pre-stored video image;
[0040] Specifically, a video image of the current scene can be collected by a camera for subsequent processing, or a pre-stored video image can be obtained from a local database.
[0041] S2: divide the video image into color information and brightness information;
[0042] Specifically, the currently collected video image or the original file obtained locally is subjected to streaming processing, and the video file is divided into a color stream and a brightness stream.
[0043] S3: Estimate the collection scene of the video image according to the color information and brightness information;
[0044] Analyzing the above-mentioned vid...

The invention relates to a video image self-adaption sharpening processing method and a device thereof. The video image self-adaption sharpening processing method is characterized in that currently-acquired video images or pre-stored video images are acquired; the video images are divided into color information and brightness information; the acquisition scenes of the video images are estimated according to the color information and the brightness information; according to the estimated acquisition scenes and the pre-stored video parameter standards corresponding to the scenes, the sharpening processing of the video images is carried out. The technical scheme provided by the invention is advantageous in that the shooting environment, and the brightness, the color, and other environmental information of the videos can be identified automatically, and whether the information is in the proper video parameter standard area can be determined by adopting the fuzzy control principle, and the corresponding sharpening algorithm can be automatically selected for the videos required to be processed, and then the videos can be stored or displayed in a sharper way, and therefore the requirement of the sharpening processing of the video images of various scenes can be satisfied, and the defect of the prior art of the sharpening processing only aiming at one scene can be solved.
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 a video picture. Background technique [0002] With the rapid development of computer networks and multimedia technologies, the application of video is changing people's lives and becoming an indispensable part of our lives. The current 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, due to the long-term copying, transmission, format conversion, and display of the video, the video quality is low. At the same time, due to the influence of lighting conditions, the contrast and color ...
