• determine a theme associated with masks previously used by the user;
• select, based on the social data of the first user, a mask from a plurality of masks, wherein the plurality of masks comprise masks stored in a database and corresponding to a mapping table, the mapping table associating the identified emotion with one or more masks of the plurality of masks, the plurality of masks being indicated by the social data as being previously selected by friends of the first user within the online social network, and wherein selecting a mask from the plurality of masks is based on the social data of the first user and the determined theme associated with the masks previously used by the user and the identified emotion of the first user in the input image, wherein the mask specifies one or more mask effects;
• and
• apply the selected mask to the first user in the input image.
