摘要

A method ( 100 ) and system ( 600 ) for adaptively segmenting pixel elements in an image frame is disclosed. The method comprises the steps of segmenting pixel elements into at least one first region based on a selection criteria ( 110 ), refining the selection criteria ( 150 ) based on information associated with each of the pixel elements within an associated first region and segmenting ( 160 ) the image pixel elements into at least one second region based on said refined selection criteria ( 150 ).
