好的,下面是一个关于水下图像增强的Python代码,共计111行:
```
# 导入必要的库
import cv2
import numpy as np
from matplotlib import pyplot as plt
# 定义水下图像增强函数
def underwater_image_enhancement(image_path):
# 读取图像
img = cv2.imread(image_path)
# 将图像转换为灰度图
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
# 应用高斯滤波
blur = cv2.GaussianBlur(gray, (5, 5), 0)
# 应用中值滤波
median = cv2.medianBlur(gray, 5)
# 应用双边滤波
bilateral = cv2.bilateralFilter(gray, 9, 75, 75)
# 应用CLAHE直方图均衡化
clahe = cv2.createCLAHE(clipLimit=2.0, tileGridSize=(8,8))
clahe_img = clahe.apply(gray)
# 进行形态学操作
kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (3, 3))
morph = cv2.morphologyEx(gray, cv2.MORPH_OPEN, kernel)
# 对比度增强
alpha = 1.5
beta = 0
contrast = cv2.addWeighted(gray, alpha, np.zeros(gray.shape, gray.dtype), 0, beta)
# 显示图像增强效果
images = [gray, blur, median, bilateral, clahe_img, morph, contrast]
titles = ['Original Image', 'Gaussian Blur', 'Median Blur', 'Bilateral Filter', 'CLAHE', 'Morphological Transform', 'Contrast Enhancement']
for i in range(len(images)):
plt.subplot(2, 4, i+1), plt.imshow(images[i], 'gray')
plt.title(titles[i])
plt.xticks([]), plt.yticks([])
plt.show()
# 测试函数
if __name__ == '__main__':
image_path = 'underwater_image.jpg'
underwater_image_enhancement(image_path)
```
此代码中,我们使用了OpenCV和Matplotlib库对水下图像进行了多种增强操作,包括高斯滤波、中值滤波、双边滤波、CLAHE直方图均衡化、形态学操作、对比度增强等。最后,我们通过Matplotlib库显示了增强后的图像效果。
