**Solution:**

Let the predicate be,

$ \max \{g(x, y)\}-\min \{g(x, y)\}\ltt_h \text {. } $

where $t_h$ is the threshold. consider $t_h \leq 3$,

$ \begin{aligned} &\therefore P\left(R_i\right)=\max \{g(x, y)\}-\min \{g(x, y)\}\lt3 \\ &(x, y \in R)(x, y \in R) \end{aligned} $

Assume 4 connectivity Let us start with the seed pixel 6 after that select seed pixel 0 and then seed pixel 3.

5 | 6 | 6 | 6 | 7 | 7 | 6 | 6 |
---|---|---|---|---|---|---|---|

6 | 7 | 6 | 7 | 5 | 5 | 4 | 7 |

6 | 6 | 4 | 4 | 3 | 2 | 5 | 6 |

5 | 4 | 5 | 4 | 2 | 3 | 4 | 6 |

0 | 3 | 2 | 3 | 3 | 2 | 4 | 7 |

0 | 0 | 0 | 0 | 2 | 2 | 5 | 6 |

1. | 1 | 0 | 1 | 0 | 3 | 4 | 4 |

1 | 0 | 1 | 0 | 2 | 3 | 5 | 4 |

Thus this image is segmented into 3 different regions by using a different seed point.
