Subject: Used euler3DTransform instead of CenteredEulerTransform. Similar result
X-Git-Tag: v1.4.0~164^2~38^2~4
X-Git-Url: https://git.creatis.insa-lyon.fr/pubgit/?a=commitdiff_plain;h=fa8617df448e18fed2f7e85a1f20726cc08103a0;p=clitk.git

Used euler3DTransform instead of CenteredEulerTransform. Similar result
but more consistent with Elastix.
