2009-3-19 Region Growing Region growing is a procedure that groups pixels or subregions into larger regions. The simplest of these approaches is pixel aggregation, which starts with a set of seed points and from these grows regions by appending to each seed points those neighboring pixels that have similar properties such as gray

Image segmentation in digital mammography

Region growing by pixel aggregation is a well known method of segmentation in the image processing field 14, 18. Reported applications of the method in medical imaging include segmentation of magnetic resonance images of the head or neck 19 and calcification detection in mammograms 20.

A new minimum variance region growing algorithm

Abstract Region growing is a very useful technique for image segmentation. Its efficiency mainly depends on its aggregation criterion. In the present paper, a new algorithm is proposed with a homogeneity criterion based on an adequate tuning between spatial neighbourhood and histogram neighbourhood. It differs from other techniques by reconsidering the pixel or voxel assignments on each step ...
