Function | Description |

coordtiff() | Extraction of X, Y coordinates from a Tiff image. Representation of the image using the first n harmonics. One image process. |

image.to.coords() | Extraction of X, Y coordinates from a Tiff image. Faster algorithm for extracting coordinates from multiple images. |

e.fourier.graph() | Represents a Tiff image using n harmonics. |

automatic.PCAfourier.analysis1() | Perform an automatic multivariate (PCA) of the EFD coefficients and geometric image analysis (euclidean distance and medoids) from the extracted coordinates matrix or a coordinate file. One image process. |

automatic.PCAfourier.analysis2() | Second version of the last function with the parameters adapted to be called from apply() and analyse multiple images at the same time (see the examples for further information). |
