Problems solved by technology

[0003] For example, adding flame special effects to videos is favored by many users, but currently the algorithms for implementing flame special effects in videos are relatively complicated, the calculation efficiency is low, and a large amount of system resources are consumed, which will cause the video display with flame special effects to be inaccurate. Smooth, not as expected

Embodiment Construction

[0060] The flow chart of method S100 for realizing flame special effects in video in a preferred embodiment of the present invention is as follows figure 1 As shown, the method S100 can be implemented by software, hardware or a combination of software and hardware. The above method S100 starts at step S110. In step S120, read a frame of video image data, initialize the size of the flame image to be added according to the size of the video image, set the flame image parameters, including the position parameter of the flame image in the video image, the height parameter of the flame image and Width parameter, and store; In step S130, generate the corresponding flame image data of video image, and store in the flame data storage module; In step S140, according to the position parameter of flame image in video image, and flame image height parameter and width parameter, the flame image data of current storage in the flame data storage module is superimposed in the video image; In...

Abstract

The invention relates to a method and a device for realizing a special flame effect in a video, wherein the method comprises the steps of: A. reading a frame of video image data, initializing the dimension of a flame image to be added according to the dimension of the video image, and setting and storing a position parameter, a height parameter and a width parameter of the flame image in the video image; B. generating flame image data corresponding to the video image, and storing the flame image data in a flame data storing module; C. superposing the flame image data currently stored in the flame data storing module in the video image; D. deleting the flame image data currently stored in the flame data storing module, judging whether reading all video images to be added with special flame effects, if so, ending the operation; if not, repeating the step A, and reading the next frame of video image data. The method and the device disclosed by the invention have the advantages of adding special effects in the video images in real time, previewing the video images in real time, and having higher calculation efficiency.

Description

technical field [0001] The invention relates to video image processing technology, more specifically, to a method and device for realizing flame special effects in video. Background technique [0002] In order to beautify the software interface and improve the visual effect of the software, in general commercial software, almost every image is displayed with image special effects, such as the screen saver of Windows system, which uses various image special effects to display , making people feel refreshed. [0003] For example, adding flame special effects to videos is favored by many users, but currently the algorithms for implementing flame special effects in videos are relatively complicated, the calculation efficiency is low, and a large amount of system resources are consumed, which will cause the video display with flame special effects to be inaccurate. Fluid, doesn't work as expected. Therefore, how to improve the calculation efficiency in the process of adding fla...
