A R package to implement the probabilistic principal curve with length penalty and fixed starting and ending point. This package includes both the 2D and 3D version.
A shiny app has been built for this package, please refer to ppclpShiny
ppclp2D
:This function implements the probabilistic principal curve with length penalty(ppclp) algorithm in 2D image
ppclp3D
:This function implements the probabilistic principal curve with length penalty(ppclp) algorithm in 3D image
spectExample
: A list, containing data of one 2D "3" number from MNIST dataset, including the x, y coordinates, start point, end point.
threeExample
: A list, containing data from one 3D SPECT on colon image, including the x, y, z coordinates, start point, end point.
Load the package into R

Load MNIST data into R from the package ppclp
library(ppclp)
data("threeExample")
Compute the principal curve
tmpCurve = ppclp2D(threeExample$x, threeExample$y, threeExample$xFix, threeExample$yFix)
Plot the final result
plot(threeExample$x, threeExample$y, xlim = c(0,1), ylim = c(0,1), pch = 16, cex = 0.8)
lines(tmpCurve$xFit, tmpCurve$yFit, type = "l", col = "red", lwd = 5)
