以下是通过Python代码实现对一张图片进行几何平移攻击的步骤:
1.导入相关模块
```python
import cv2
import numpy as np
```
2.读取图片并显示
```python
img = cv2.imread("picture.jpg")
cv2.imshow("Original", img)
cv2.waitKey(0)
```
3.定义平移矩阵
```python
rows, cols = img.shape[:2]
M = np.float32([[1, 0, 100], [0, 1, 50]]) # 向右平移100,向下平移50
```
4.执行平移操作并显示结果
```python
img_translation = cv2.warpAffine(img, M, (cols, rows))
cv2.imshow("Translation", img_translation)
cv2.waitKey(0)
```
完整代码:
```python
import cv2
import numpy as np
img = cv2.imread("picture.jpg")
cv2.imshow("Original", img)
cv2.waitKey(0)
rows, cols = img.shape[:2]
M = np.float32([[1, 0, 100], [0, 1, 50]]) # 向右平移100,向下平移50
img_translation = cv2.warpAffine(img, M, (cols, rows))
cv2.imshow("Translation", img_translation)
cv2.waitKey(0)
```
注意:在代码中,我们可以根据需要自定义平移矩阵中的参数来实现不同的平移操作。
