Linux 部署 AI 换脸

在Linux上部署AI换脸通常需要使用一些特定的库，如OpenCV、dlib或者深度学习框架如TensorFlow或PyTorch。以下是一个基于Python和深度学习框架TensorFlow的简单示例。

1. 安装必要的库：

pip install tensorflow-gpu opencv-python-headless dlib

2. 准备模型，可以使用已经训练好的模型如“face-recognition”库中的模型，或者自己训练。
3. 编写换脸代码：

import cv2
import dlib
import numpy as np
import tensorflow as tf
import tensorflow_hub as hub
 
# 加载TensorFlow Hub模型
hub_model = 'https://tfhub.dev/deepmind/deeppixel-celeba/1'
 
# 初始化模型
module = hub.Module(hub_model)
 
# 加载dlib人脸检测器和68点标记点检测器
detector = dlib.get_frontal_face_detector()
predictor = dlib.shape_predictor('shape_predictor_68_face_landmarks.dat')
 
# 读取图片
def load_image_file(file_path, max_dimension=1024):
    image = cv2.imread(file_path)
    image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)
    image_shape = image.shape
    image_dims = []
    for dim in image_shape:
        if dim > max_dimension:
            image_dims.append(max_dimension)
        else:
            image_dims.append(dim)
    image = cv2.resize(image, tuple(image_dims), interpolation=cv2.INTER_AREA)
    return image
 
# 换脸
def swap_faces(source_image_path, target_image_path, output_image_path):
    source_image = load_image_file(source_image_path)
    target_image = load_image_file(target_image_path)
 
    # 检测人脸
    source_faces = detector(source_image, 1)
    target_faces = detector(target_image, 1)
 
    if len(source_faces) < 1 or len(target_faces) < 1:
        raise Exception('No faces found.')
 
    # 获取人脸的68点标记
    source_landmarks = predictor(source_image, source_faces[0])
    target_landmarks = predictor(target_image, target_faces[0])
 
    # 获取变换矩阵
    source_points = np.matrix([[p.x, p.y] for p in source_landmarks.parts()])
    target_points = np.matrix([[p.x, p.y] for p in target_landmarks.parts()])
    transformation_matrix = _get_transformation_matrix(source_points, target_points)
 
    # 应用变换
    source_image_warped = cv2.warpAffine(source_image, transformation_matrix, target_image.shape[:2])
 
    # 融合图像
    alpha = 0.6
    output_image = (1 - alpha) * target_image + alpha * source_image_warped
 
    # 保存结果
    cv2.imwrite(output_image_path, output_image)
 
# 获取变换矩阵的辅助函数
def _get_transformation_matrix(source_points, target_points):
    # 此处应该是用于计算变换矩阵的代码，可以使用OpenCV的函数cv2.estimateRigidTransform()
    pass
 
# 使用模型进行换脸
def transform_image(sour
