abstract = "The notion of {\^A}strength of connectedness{\^A} between pixels
has been successfully used in image segmentation. We present an
extension to these works, which can considerably increase the
efficiency of object definition tasks. A set of pixels is said a
k-connected component with respect to a seed pixel when the
strength of connectedness of any pixel in that set with respect to
the seed is higher than or equal to a threshold. While the
previous approaches either assume no competition with a single
threshold for all seeds or eliminate the threshold for seed
competition, we found that seed competition with different
thresholds can reduce the number of seeds and the need for user
interaction during segmentation. We also propose automatic and
user-friendly interactive methods for determining the thresholds.
The improvements are demonstrated through several segmentation
experiments involving medical images.",
