I am just curious what kind of method used in peak searching during image process. for example searching the CCF peak.

The most straightforward way I am aware of is to find the voxel in the CCF which has the highest value, and then least-squares fit a paraboloid function in the 3x3x3-voxel cube centered around that voxel to find the peak's non-integer coordinates.

I'd be interested in finding out about other ways...
