antsAverageImages.Rd
Calculate the mean of a list of antsImages
antsAverageImages(imageList, normalize = FALSE, weights)
imageList | list of antsImages or a character vector of filenames |
---|---|
normalize | boolean determines if image is divided by mean before averaging |
weights | a vector of weights of length equal to imageList |
