## 型態學影像處理

深綠色投影片作者: 台科大黃正民教授

---

### 型態學影像處理的基本概念
型態學的處理可以用於
簡化影像資料
保留重要的形狀特性
消除雜訊(不相關的部分)
灰階影像 --> 二值化影像 --> 型態學 --> 連通元件

## 膨脹處理
![[Pasted image 20240828160329.png]]

---

## 膨脹處理
滿足交換律
A ⊕ B == B ⊕ A
滿足結合律
(A ⊕ B ) ⊕ C == A ⊕ (B ⊕ C)
位移不變性
A ⊕ B_z == (A ⊕ B )_z
應用
文字辨識

## 斷開與閉合
斷開: 先侵蝕再膨脹
閉合: 先膨脹再侵蝕

### 車牌影像偵測
在固定環境下,車牌辨識的 成果已經非常完善
在環境較多干擾的情況·車 牌辨識的成功率會大幅降低

---
### 車道標線影像偵測
為了彌補路面或車道標線反光、 陰影遮蔽等造成偵測的圖像破碎, 使部分車道線無法成功找到的問題
使用形態學去除雜訊干擾、填補車道線破碎的部分
