Image object of S4 class 'antsImage' to be coerced.
mask
logical vector/matrix/array to be used as mask while extracting pixel values from the image. 1/TRUEs return corresponding pixel values ; 0/FALSEs return NA. The vector provided will be 'matched' against the image-region column-wise meaning that first column of image-region is extracted using first column-length values from the vector, second column is extracted using the next column-length values from the vector and so on. Default: entire region is extracted.
region
antsRegion with in the antsImage to be considered for extraction. An antsRegion object can be created using new. Default: largest-possible-region( entire image ) in the image.
Value
numeric vector of dimensions equal to that of 'region' considered – Success ; NA – Failure
