Embodiment Construction

[0075] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0076] refer to figure 2 , which shows a flowchart of an embodiment of an automatic video color coordination processing method according to the present invention, which includes:

[0077] Step 21, the video file is divided into each segment of shot video;

[0078] A video file is composed of shot videos one by one in chronological order. A shot video describes the activity of a target object in a certain scene, and the switching of shots usually represents the switching of scenes. The acquisition of each shot video in the video file is detected by the position of the shot switch. It divides the video file into a shot video one by one. Each shot video is divided into frames, and each frame is a still image, in rapid succession. ...

Abstract

The invention provides an automatic video color coordination processing method and a processing system thereof. The automatic video color coordination processing method includes steps of cutting a video file into lens video sections, reading in a lens video section, performing color coordinating process on each frame in current lens video section according to a matching coordinated color template of a first frame and time and space neighborhood points of pixels of each frame, wherein the time and space neighborhood points comprise space neighborhood points and time neighborhood points, further, judging whether the current lens video section is the last lens video section of the video filer or not, if not, then executing the previous step, and if so, then completing the process of the video file. Besides, the invention further provides an automatic real-time video color coordination processing method. As all the frames in one lens video section correspond to the same coordinated color template, and the color coordinating result of the front frame is utilized as a foundation of color coordination of the current frame, space continuity and time continuity of color coordination of each frame in one lens video section are guaranteed.

Description

technical field [0001] The invention relates to the technical fields of digital image processing and computer vision, in particular to an automatic video color coordination processing method and processing system. Background technique [0002] From an aesthetic point of view, the so-called coordinated color (hereinafter referred to as coordinated color) refers to a set of colors that can visually give people a sense of beauty. This group of colors is not composed of specific colors, but determined by their relative positional relationship in the color space. [0003] There are many definitions of coordinated colors, but the most widely used one is the color wheel model proposed by Matsuda in the document "Color Design" in 1995. In this document, the author expresses the hue as a circle, and the hue of the coordinated color is defined as 8 templates composed of fans of different sizes, such as figure 1 As shown in , the hues represented by the fan-shaped areas in each templ...
