为了得到永恒、连续、更高真实感的流体视频,分析已有视频合成技术,提出了一种基于粒子系统的流体视频合成方法。该方法针对具有持续流动模式的流体,在保持其自然外观和复杂性的同时,将具有固定长度的视频样本编辑成为具有新的形态的更加真实、有生气的任意长度的无缝视频。首先,分析视频样本中粒子的运动规律,将输入序列用粒子纹理矩阵表示;其次,改变粒子纹理矩阵内容,生成新的播放序列;再次,应用已得到的新的粒子状态信息,在新的区域编辑合成新的播放序列,得到更加真实生动的流体视频;最后,利用这一算法开发了流体视频合成编辑器软件,并应用到视频样本上。实验结果表明,这种基于粒子系统的流体视频合成方法不仅合成速度快,合成的视频纹理效果更好,并且易于实现。
In order to get eternal
continuous and active continuous flow video
analyzing several video synthesis technologies
this paper presents a new particle system based on continuous flow video synthesis method which could process sample videos of continuous flow
and synthesize more realistic seamless video of arbitrary length than other algorithms. Based on the particles movement rules in the video sample
the input sequence is represented by particle texture matrix. The particle texture matrix is modified
and new sequence is synthesized. A new particle texture matrix is edited to new region and more realistic and active flow video is synthesized. The continuous flow video synthesis editor software is developed by this way
and is applied to video sample. The experimental results show that this synthesis method has the characteristics such as the higher speed calculation
better synthetic effect than before
and it is easy to implement.
