Problems solved by technology

Although the visual effect of each frame of the work completed in this production mode can be manually controlled, the continuous play causes a large jitter phenomenon in the video picture due to the lack of consistency between frames, and these methods have a long production cycle and high cost. High, not conducive to mass production
For example, although the oil painting short film of "The Old Man and the Sea" mentioned above is only 22 minutes long, the production cycle is as long as nearly 3 years

Embodiment

[0095] The interactive video stylization rendering method based on video interpretation of the present invention includes an interactive video semantic segmentation module and a video stylization module, and the segmentation method of the interactive video semantic segmentation module includes the following steps:

[0096] 1) Interactive segmentation and automatic recognition of key frame images;

[0097] 2) Matching of dense feature points between key frames;

[0098] 3) Regional competition segmentation algorithm;

[0099] The stylization method of the video stylization module comprises the following steps:

[0100] 4) Non-realistic rendering of key frames based on semantic analysis;

[0101] 5) stroke propagation method of sequence frame;

[0102] 6) Damping brush system for anti-shake.

[0103] The stylization of the video will use these two modules in turn. That is, the video is first semantically segmented using an interactive semantic segmentation module. Then use...

Abstract

The invention relates to an interactive video stylized rendering method based on video interpretation, wherein an interactive video semantic segmentation module and a video stylization module are utilized. A segmentation method of the interactive video semantic segmentation module comprises the following steps of: (1) interactive segmentation and automatic identification of key frame images; (2) matching of dense characteristic points among key frames; and (3) area competition segmentation. A stylization method of the video stylization module comprises the following steps of: (4) un-reality sense drawing of the key frames based on semantic analysis; (5) a brushwork propagating method of a sequence frame; and (6) a damping pen brush system for preventing shaking. The interactive video stylized rendering method based on the video interpretation, disclosed by the invention, has the advantages of short manufacturing period, low cost and favorability on manufacturing in batches.

Description

technical field [0001] The invention is an interactive video stylized rendering method based on video interpretation, which belongs to the transformation technology of the interactive video stylized rendering method based on video interpretation. Background technique [0002] With the popularization of computers, digital cameras and digital video cameras, people's demand for audio-visual entertainment is getting higher and higher. What followed was the vigorous development of the home digital entertainment field. More and more people are beginning to try to become amateur "directors", keen to produce and edit various ordinary realistic videos. In recent years, various stylized videos have gradually been accepted by people and become popular elements, especially in the production of animated videos and online games. For example, the hand-painted oil painting short film "The Old Man and the Sea" and the ink painting video "Little Tadpole Looking for Mother" have attracted wi...
