A generation method and a generation system of a fixed-frame animation

Abstract

The invention belongs to the technical field of computer application, and particularly relates to a generation method and a generation system of a fixed-frame animation. The generation method includes: Opening an initialization frame buffer, and mapping a frame buffer device address to a storage mapping address; Opening a video equipment file; Obtaining equipment information; changing Relevant settings of the equipment according to needs; Acquiring the acquired image data; Extracting video data frames; And connecting the extracted plurality of video data frames according to a time sequence togenerate a fixed-frame animation. The animation processing efficiency is high, the redundancy is low, and the real-time response is fast by adopting streaming processing. According to the invention, the storage stores one frame of picture and establishes the mapping relation between the picture and the address; An improved image compression algorithm is adopted to compress each frame of image, andon the basis that a high compression ratio can be obtained and the visual effect of the compressed image is basically the same as that of an original image, the peak signal to noise ratio and the subjective visual quality of the image are further improved.

Description

technical field [0001] The invention belongs to the technical field of animation processing, in particular to a method and system for generating stop-motion animation. Background technique [0002] Stop-motion animation is the process of shooting a subject frame by frame and then showing it in succession, thereby producing as if alive a character or any bizarre character you can imagine. What is commonly referred to as stop-motion animation is generally performed by clay puppets, puppets, or mixed-material characters. The history of this form of animation is as long as the history of hand-drawn animation (Cel Animation) in the traditional sense, and may even be older. [0003] In summary, the problems in the prior art are: [0004] (1) In the prior art, the method of centralized computer production and manual interception of video information by the operator is often adopted. The stop-motion animation formed by this method has high redundancy, high repetition, low efficie...

AI Technical Summary

Problems solved by technology

The stop-motion animation formed by this method has high redundancy, high repetition, low efficiency and poor effect

[0005] (2) In the process of caching video pictures in the frame buffer in the prior art, traditional algorithms are used to cache the pictures, which cannot effectively improve the cache performance of search applications, reduce the picture hit rate and reduce the average delay time

[0006] (3) In the process of periodic sampling of continuous frame images in the frame buffer by the image reading device in the prior art, the existing recognition algorithm is used to recognize the image, which improves the recognition speed and cannot guarantee the recognition accuracy and algorithm Robustness, not good adaptability to occlusion and interference images

[0007] (4) In the process of storing pictures frame by frame in the prior art and establishing the mapping relationship between pictures and addresses, traditional algorithms are used to compress the pictures of each frame, and a higher compression ratio can be obtained. On the basis that the compressed image has basically the same visual effect as the original image, the peak signal-to-noise ratio and subjective visual quality of the image cannot be effectively improved.
