cropIndices: crop a sub-image by image indices

In stnava/ANTsR: ANTs in R: Quantification Tools for Biomedical Images

crop a sub-image by image indices

Description

create a proper antsImage sub-image by indexing the image with indices. this is similar to but different from array sub-setting in that the resulting sub-image can be decropped back into its place without having to store its original index locations explicitly.

Usage

cropIndices(image, lowerind, upperind)

Arguments

image	antsImage to crop
lowerind	vector of lower index, should be length image dimensionality
upperind	vector of upper index, should be length image dimensionality

Value

subimage

Examples

fi <- antsImageRead(getANTsRData("r16"))
cropped <- cropIndices(fi, c(10, 10), c(100, 100))
cropped <- smoothImage(cropped, 5)
decropped <- decropImage(cropped, fi)
