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).
