关于abel 变换
利用相机拍摄火焰,得到的其实是一个三维强度的叠加,现在要得到火焰的刨面强度图需要进行abel变换,现在我在网上找了一个代码但是怎么运行都有错误,不知道怎么弄啊!!已知运行这段代码需要输入5个变量,其中H - dataset to be analyzed (1xN - matrix). For optimum results, H(1) should be the center and H(N) the edge of the investigated object and H(N) should be approx zero If no input H is given, a sampla dataset will be created.R - radius of given system (i.e. distance between H(1) and H(N)) UPF - upper frequency limit. Defines the number of expansions (and critically determines computation Choosing a very low value (e.g. 4) results in a low- filtering effect, reducing noise (but also potential PLOT_RESULTS - set to 1 to plot the results LSQ_SOLVE - set to 1 to use LSQCURVEFIT instead of solving the least square problem - maybe useful if the of a singular matrix ocurr。H,R我大体上了解了 但是UPF 真的不知道是啥 频率上限??希望哪位大神能解释解释。 |
