POD (proper orthogonal decomposition) code in Matlab

用于对PIV获得的速度场进行背景噪点去除(We propose a novel image preprocessing method for Particle Image Velocimetry (PIV), to remove background noise sources such as time dependent light reflection, light nonuniformities or camera dark noise.)

用于对复杂流场的POD分析，对流场结构进行解构重组(PODDEM is a state of the art detection and estimation method for outliers in Particle Image Velocimetry data. PODDEM can be used on two-dimension and three dimensional data, with up to three velocity components.)

POD与DMD 降阶代码，用于提取流场主要结构(Proper Orthogonal Decomposition)
