Quantization method and system for motion of non-stationary structure in image

The invention discloses a quantization method, system and device for motion of a non-stationary structure in an image, and the method comprises the steps: S1, estimating and adjusting phase information through employing the maximum possibility of block matching 3D sparseness prior, and completing the multi-frequency phase retrieval; and S2, calculating an estimated unwrapped phase phi by using robust two-dimensional phase unwrapping, and completing the quantization of the motion of the non-stationary structure in the image. According to the invention, quantization of non-stationary structure motion in the image can be realized. 本发明公开了一种图像中非平稳结构运动的量化方法、系统及装置，包括：S1、使用块匹配3D稀疏度先验的最大可能性来估计和调整相位信息，完成多频相位检索；S2、使用鲁棒二维相位展开来计算估计的展开相位φ，完成图像中非平稳结构运动的量化。本发明可以实现图像中非平稳结构运动的量化。
