• grabcut: http://docs.opencv.org/modules/imgproc/doc/miscellaneous_transformations.html?highlight=watershed#grabcut.

• meanshift: http://docs.opencv.org/modules/imgproc/doc/filtering.html?highlight=pyrmeanshift#pyrmeanshiftfiltering

Btw: A small search in this forum could have given you exactly this answer...
