Example Embodiment

[0035] In order to facilitate the understanding of the present invention, specific embodiments will be used below to describe the present invention more fully. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing this embodiment is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0036] The video enhancement method based on video frame adaptation in an embodiment of the present invention is an adaptive video enhancement method based on spatial point algorithm, which not only guarantees performance, but also adaptively selects and adjusts parameters according to the video content, no matter how much the video content changes. , And no matter the video format, resolution, bit rate, etc., it has a good enhancement effect. Specifically, firstly, all frames in the video are acquired in sequence, the video enhance...

Abstract

The invention discloses a video enhancing method based on video frame self-adaption. The method comprises video frame self-adaption parameter adjustment and video frame enhancing processing. The invention also discloses a video enhancing system. The system comprises a parameter adjusting module and an enhancing processing module. According to the video frame self-adaptive video enhancing method based on an airspace point algorithm and the video enhancing system built based on the method, through starting from a performance and a video continuous frame enhancement flexibility, the performance is ensured; moreover, adjusting parameters are selected according to the video contents self-adaptively; the problem of video frame distortion resulting from excessively improving too dark images or excessively reducing too bright images by directly using conventional methods such as histogram equal saturability enhancing is solved; the enhancing of the processed video under various environments such as indoor, outdoor, low illumination and high illumination environments, is more flexible; and compared with the original video, the processed video is more clear in detail and more abundant in contrast and saturability and has better eye watching feelings.

Description

technical field [0001] The invention relates to a video frame self-adaptive video enhancement method and a video enhancement system. Background technique [0002] With the rapid development of the Internet in recent years, video has developed more rapidly than pictures, people's daily sharing habits have gradually shifted from picture sharing to video sharing, and more and more people will watch videos on handheld devices; on the other hand With the popularization of high-definition, the development of 4K, and the improvement of the resolution of display devices, people have higher and higher requirements for video brightness, clarity and other display effects. Therefore, video enhancement has become an indispensable means for video playback. . [0003] According to the different space where signal enhancement is located, video enhancement can be divided into frequency domain algorithm and spatial domain algorithm. Frequency domain algorithms such as FFT, DCT, etc. treat i...
