This paper presents a new robust yet very simple algorithm to find a homoge
neous region in an image. The algorithm is based on iteratively growing and
shrinking a region until a stable state of the algorithm is reached and go
od fit is found. We have shown that the algorithm works very well in color
and optical flow pictures, and overcomes some of the drawbacks of classic s
eed growing algorithms. (C) 2001 Elsevier Science B.V. All rights reserved.
