Problems solved by technology

[0004] Most of the traditional image enlargement methods are based on continuous function approximation theory, such as nearest neighbor interpolation, bilinear interpolation, bicubic interpolation and spline interpolation. The smoothing effect of the continuous interpolation function produces a transition band of gray values. This transition band causes the blurring of the high-resolution image at the edge, and finally makes the video blurred after zooming in.

Abstract

The invention discloses a video amplification method and a system based on a subdivision method, belonging to the technical field of videos. The method comprises the following steps: (1) decomposing a video into frame images; (2) obtaining the decomposed images and an amplification factor n; (3) determining required subdivision time k according to the amplification factor n; (4) labeling pixels by classification; (5) calculating gradients and twisting vectors at the pixels according to the classification labels of the pixels; (6) refining the images by using improved interpolating subdivision; (7) re-sampling the refined data according to required image resolution to obtain the sampled images; and (8) synthesizing the sampled images into a new video. The invention additionally provides a video amplification system and has the advantage that the video is clearer after the video is amplified.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video amplification method and system based on a subdivision method. Background technique [0002] In today's information age, with the development of computer technology, digital camera, network video and high-definition digital TV, digital video has increasingly become an important channel for people to obtain information. Especially with the popularization of high-definition digital TV signals in China, a large number of ordinary TV program sources need to be upgraded to high-definition digital TV programs, which increases the urgent demand for digital video amplification technology. [0003] The so-called video enlargement is to enlarge the image of each frame of the video. . For image magnification, it refers to a basic operation of obtaining high-definition images by increasing the resolution of the image. and so on have a wide range of applications. ...
