region growing:
The fundamental drawback of histogram-based region detection is that histograms
provide no spatial information (only the distribution of gray levels).
- Region-growing approaches exploit the important fact that pixels which are close
together have similar gray values.
• Region growing
- Start with a single pixel (seed) and add new pixels slowly
(1) Choose the seed pixel
(2) Check the neighboring pixels and add them to the region if they are similar to-region growing:
