Hi,
I have some trouble using the demons_registration from
https://insightsoftwareconsortium.github.io/SimpleITK-Notebooks/R_html/66_Registration_Demons.html
I have tested the example and it work well. however when i used the function
demons_registration with two image .png that i have generated i have some
strange errors. See the R code and the error below
# generate two image of a square slighty differents
library(raster)
library(imager)
r=raster(ncol=600,nrow=600)
r=setValues(r,1)
im1=as.cimg(r)
im1[200:300,200:300]=0
plot(im1)
im2=as.cimg(r)
im2[210:320,210:320]=0
plot(im2)
save.image(im1,"square1.png")
save.image(im2,"square2.png")
library(SimpleITK)
cntrl <- ReadImage("square1.png")
img1 = Cast(cntrl,"sitkFloat32")
img1
cntrl <- ReadImage("square2.png")
img2 = Cast(cntrl,"sitkFloat32")
img2
# the demons_registration function can be downloaded here :
https://insightsoftwareconsortium.github.io/SimpleITK-Notebooks/R_html/66_Registration_Demons.html
tx <- demons_registration(fixed_image = img1, moving_image = img2)
Show Traceback
Rerun with Debug
Error in f(...) : Exception in SITK - check warning messages In addition:
Warning message:

sitk::ERROR: Unexpected error converting transform! Possible miss matching

Does anyone have an idea of the problem ?
Thank you very much,
