We study the holographic mutual information in AdS4 of disjoint spatialdomains in the boundary which are delimited by smooth closed curves. Anumerical method which approximates a local minimum of the area functionalthrough triangulated surfaces is employed. After some checks of the methodagainst existing analytic results for the holographic entanglement entropy, wecompute the holographic mutual information of equal domains delimited byellipses, superellipses or the boundaries of two dimensional spherocylinders,finding also the corresponding transition curves along which the holographicmutual information vanishes.
