Python区域增长分割算法是一种基于像素相似性的图像分割方法,它通过对像素进行聚类,将相似的像素点组成一个区域,从而实现图像的分割。以下是一个简单的实验代码示例:
```python
import cv2
import numpy as np
def region_growing(image, seed):
height, width = image.shape
visited = np.zeros_like(image)
region = np.zeros_like(image)
stack = []
stack.append(seed)
while len(stack) > 0:
x, y = stack.pop()
if visited[x, y] == 1:
continue
visited[x, y] = 1
region[x, y] = image[x, y]
for i in range(-1, 2):
for j in range(-1, 2):
if 0 <= x + i < height and 0 <= y + j < width and not (i == 0 and j == 0):
if abs(int(image[x, y]) - int(image[x + i, y + j])) < 20:
stack.append((x + i, y + j))
return region
if __name__ == "__main__":
image_path = "example.jpg"
image = cv2.imread(image_path, 0)
seed = (100, 100) # 选择一个种子点
segmented_region = region_growing(image, seed)
cv2.imshow("Original", image)
cv2.imshow("Segmented Region", segmented_region)
cv2.waitKey(0)
cv2.destroyAllWindows()
```
以上代码通过使用OpenCV库读取图像,并选择一个种子点,然后利用区域增长分割算法对图像进行分割。最后使用OpenCV库展示原始图像和分割后的区域。这是一个简单的Python区域增长分割算法实验代码示例。
