Xmipp

xmipp_image_find_center (v3.0)

Usage

Find the best symmetry of rotation of an image or collection of images It is very useful when you want to calculate the rotational symmetry of a set of images (in fact it computes the center of the average image). Image dimensions must be less than 512x512.
