In bishun945/FCMm: Fuzzy Cluster Method Based on the Optimized m Value (Fuzzifier)

Description

Generate the input parameter of apply_to_image based on the built-in or user-defined centroids

Usage

generate_param(wl)

generate_param_ex(centroids, m = 1.36)

Arguments

wl	wavelength of subsetting
centroids	The centorids values required for fuzzy clustering on images. Its colnames should be converted to numeric wavelength. The format should be like Rrs_clusters.default.
m	The fuzzifier value of FCM. Default as 1.36.

Value

The return of generate_param or generate_param_ex is a list used for function apply_to_image.

Note

generate_param only support the cluster centroids proposed by Bi et al. (2019). However, the generate_param_ex could be used for user-defined centroids if you want.
