CV实现
PIL实现
使用一个函数实现两张图像合并，通过参数指定合并方式（水平或垂直或加权）。
CV实现
import cv2
import numpy as npdef merge_images_cv(image_path1, image_path2, method='horizontal', alpha=0.5):# 读取图像img1 = cv2.imread(image_path1)img2 = cv2.imread(image_path2)# 确保 alpha 在 0 和 1 之间alpha = max(0, min(alpha, 1))if method == 'horizontal':# 调整 img2 到 img1 的高度img2 = cv2.resize(img2, (img2.shape[1], img1.shape[0]))# 水平合并merged_img = np.hstack((img1, img2))# merged_img = np.concatenate((image1, image2), axis=1)elif method == 'vertical':# 调整 img2 到 img1 的宽度img2 = cv2.resize(img2, (img1.shape[1], img2.shape[0]))# 垂直合并merged_img = np.vstack((img1, img2))# merged_img = np.concatenate((image1, image2), axis=0)elif method == 'weighted':# 加权合并，确保两张图像大小相同img2 = cv2.resize(img2, (img1.shape[1], img1.shape[0]))# 加权合并merged_img = cv2.addWeighted(img1, alpha, img2, 1 - alpha, 0)else:raise ValueError("Method must be 'horizontal', 'vertical', or 'weighted'")return merged_img# 使用示例
merged_image = merge_images_cv('path_to_first_image.jpg', 'path_to_second_image.jpg', method='horizontal')
cv2.imwrite('merged_image.jpg', merged_image)PIL实现
from PIL import Imagedef merge_images_pil(image_path1, image_path2, method='horizontal', alpha=0.5):# 打开图像img1 = Image.open(image_path1)img2 = Image.open(image_path2)# 确保 alpha 在 0 和 1 之间alpha = max(0, min(alpha, 1))if method == 'horizontal':# 调整 img2 到 img1 的高度img2 = img2.resize((img2.width, img1.height))# 水平合并merged_img = Image.new('RGB', (img1.width + img2.width, img1.height))merged_img.paste(img1, (0, 0))merged_img.paste(img2, (img1.width, 0))elif method == 'vertical':# 调整 img2 到 img1 的宽度img2 = img2.resize((img1.width, img2.height))# 垂直合并merged_img = Image.new('RGB', (img1.width, img1.height + img2.height))merged_img.paste(img1, (0, 0))merged_img.paste(img2, (0, img1.height))elif method == 'weighted':# 加权合并，确保两张图像大小相同img2 = img2.resize((img1.width, img1.height))# 加权合并merged_img = Image.blend(img1, img2, alpha)else:raise ValueError("Method must be 'horizontal', 'vertical', or 'weighted'")return merged_img# 使用示例
merged_image = merge_images_pil('path_to_first_image.jpg', 'path_to_second_image.jpg', method='horizontal')
merged_image.save('merged_image.jpg')
