基于深度学习的红外图像和可见光图像的融合python

红外图像和可见光图像融合可以提高图像的质量和信息丰富度，可以应用于很多领域，比如目标检测、识别和追踪等。下面是一个基于深度学习的红外图像和可见光图像融合的Python实现示例：

1. 安装必要的库：

pip install opencv-python numpy tensorflow keras

2. 加载红外图像和可见光图像：

import cv2
import numpy as np

infrared = cv2.imread('infrared_image.jpg', 0)
visible = cv2.imread('visible_image.jpg', 0)

3. 对图像进行预处理：

infrared = cv2.resize(infrared, (256, 256))
visible = cv2.resize(visible, (256, 256))

infrared = infrared.astype(np.float32) / 255
visible = visible.astype(np.float32) / 255

infrared = np.expand_dims(infrared, axis=2)
visible = np.expand_dims(visible, axis=2)

input_data = np.concatenate((infrared, visible), axis=2)

4. 定义模型：

from keras.models import Model
from keras.layers import Input, Conv2D, MaxPooling2D, UpSampling2D, Concatenate, BatchNormalization

input_layer = Input(shape=(256, 256, 2))

# 编码器
conv1 = Conv2D(32, (3, 3), activation='relu', padding='same')(input_layer)
conv1 = Conv2D(32, (3, 3), activation='relu', padding='same')(conv1)
pool1 = MaxPooling2D((2, 2))(conv1)

conv2 = Conv2D(64, (3, 3), activation='relu', padding='same')(pool1)
conv2 = Conv2D(64, (3, 3), activation='relu', padding='same')(conv2)
pool2 = MaxPooling2D((2, 2))(conv2)

conv3 = Conv2D(128, (3, 3), activation='relu', padding='same')(pool2)
conv3 = Conv2D(128, (3, 3), activation='relu', padding='same')(conv3)
pool3 = MaxPooling2D((2, 2))(conv3)

# 解码器
up4 = UpSampling2D((2, 2))(pool3)
conv4 = Conv2D(128, (3, 3), activation='relu', padding='same')(up4)
conv4 = Conv2D(128, (3, 3), activation='relu', padding='same')(conv4)

up5 = UpSampling2D((2, 2))(conv4)
conv5 = Conv2D(64, (3, 3), activation='relu', padding='same')(up5)
conv5 = Conv2D(64, (3, 3), activation='relu', padding='same')(conv5)

up6 = UpSampling2D((2, 2))(conv5)
conv6 = Conv2D(32, (3, 3), activation='relu', padding='same')(up6)
conv6 = Conv2D(32, (3, 3), activation='relu', padding='same')(conv6)

merge7 = Concatenate(axis=3)([conv6, conv1])
conv7 = Conv2D(32, (3, 3), activation='relu', padding='same')(merge7)
conv7 = Conv2D(32, (3, 3), activation='relu', padding='same')(conv7)

output_layer = Conv2D(1, (1, 1), activation='sigmoid', padding='same')(conv7)

model = Model(inputs=input_layer, outputs=output_layer)

5. 训练模型：

model.compile(optimizer='adam', loss='mse')

model.fit(input_data, infrared, batch_size=32, epochs=100)

6. 进行图像融合：

output = model.predict(input_data)

output = output.squeeze()
output = output * 255
output = output.astype(np.uint8)

cv2.imwrite('fusion_image.jpg', output)

以上就是一个基于深度学习的红外图像和可见光图像融合的Python实现示例，你可以根据自己的需求进行调整和改进。
