Document Type and Number:
Japanese Patent JP2005535028
Kind Code:
A
Abstract:
A segmentation system ( 100 ) for segmenting a first image feature ( 214 ) in a first video image from an adjacent second image feature ( 216 ) in the first video image on basis of motion and on an image property like color or luminance. The segmentation system ( 100 ) comprises; a block-based motion estimator ( 102 ) for estimating motion vectors ( 218 - 230 ) for blocks of pixels; a motion segmentation unit ( 104 ) for segmenting the first video image into a first group of connected blocks of pixels ( 204 ) and a second group of connected blocks of pixels ( 206 ) on basis of the motion vectors ( 218 - 230 ) of the respective blocks of pixels; and a pixel-based segmentation unit ( 106 ) for segmenting the first image feature ( 214 ) from the second image feature ( 214 ) by means of a pixel-based segmentation of a portion of the blocks of pixels of the first and second group of connected blocks of pixels ( 214 and 216 ), on basis of the respective values of the image property.
