单帧投影条纹图像的相位恢复是条纹投影测量中的一个重要问题，也是一个具有挑战性的问题。本文提出了一种基于变分图像分解(VID)的单帧投影条纹图像相位恢复的新方法。提出了一种新的图像分解模型TV-G-Searlet，以有效地将投影条纹图像分解为背景部分、条纹部分和噪声部分。通过仿真和实际投影条纹验证了该方法的性能，并与目前广泛使用的傅里叶变换方法和小波变换方法进行了比较。(C)2014爱思唯尔有限公司。保留所有权利。
Phase retrieval from single frame projection fringe pattern is of fundamental importance, and is also a challenging problem in fringe projection measurement. In this paper, we present a new method for phase retrieval from a single frame projection fringe pattern based on variational image decomposition (VID) methods. We propose a new image decomposition model TV-G-Shearlet in order to effectively split a projection fringe pattern into background part, fringe part and noise part. The performance of the proposed approach is verified by simulated and real projection fringes as well as the comparison with the widely used and well-known Fourier transform method and wavelet transform method.
