*Region Grow

Segmentation > *Region Grow

Requires B/W Companion Image

Grows each seed (features in Companion Image) until the specified percentage of new pixels do not fall within the threshold pixel-value distance from the seed pixel value. Seeds are are obtained from the features in the Companion Image.

1. Use

• Entire Seeds: Use entire seeds for region growing. Entire seed will be superimposed on each region after growing. Region growing will still start from seed centroids.
• Centroids: Use centroid of each seed for region growing.

2. Tolerance

Tolerance for region growing. Only pixels within the tolerance threshold of the seed pixel get added to the region.
