四、AI抠图算法升级

1. 深度学习抠图模型

import cv2
import numpy as np

class DeepMatting:
    def __init__(self, model_path):
        # 加载深度学习模型
        self.net = cv2.dnn.readNetFromONNX(model_path)
        
    def remove_background(self, image):
        # 预处理
        blob = cv2.dnn.blobFromImage(image, scalefactor=1/255.0, size=(512, 512), 
                                     mean=(0.485, 0.456, 0.406), swapRB=True)
        
        # 推理
        self.net.setInput(blob)
        output = self.net.forward()
        
        # 后处理
        mask = output[0, 0]  # 获取alpha通道
        mask = cv2.resize(mask, (image.shape[1], image.shape[0]))
        mask = (mask * 255).astype(np.uint8)
        
        # 应用掩码
        result = cv2.cvtColor(image, cv2.COLOR_BGR2BGRA)
        result[:, :, 3] = mask
        
        return result

2. 边缘优化算法

def refine_edges(image, mask):
    """优化抠图边缘"""
    # 边缘检测
    edges = cv2.Canny(mask, 100, 200)
    
    # 膨胀操作
    kernel = np.ones((3, 3), np.uint8)
    dilated = cv2.dilate(edges, kernel, iterations=1)
    
    # 创建过渡区域
    transition = np.zeros_like(mask, dtype=np.float32)
    transition[dilated > 0] = 0.5
    
    # 应用过渡
    alpha = mask.astype(np.float32) / 255.0
    alpha = np.clip(alpha + transition, 0, 1)
    
    # 更新图像
    result = image.copy()
    result[:, :, 3] = alpha * 255
    
    return result

五、高级功能：智能美颜与增强

1. 人脸检测与关键点定位

def detect_faces(image):
    """检测人脸并返回关键点"""
    # 加载预训练模型
    face_detector = cv2.CascadeClassifier(cv2.data.haarcascades + 'haarcascade_frontalface_default.xml')
    gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
    
    # 检测人脸
    faces = face_detector.detectMultiScale(gray, 1.3, 5)
    
    # 检测关键点 (使用dlib或OpenCV Facemark)
    landmarks = []
    for (x, y, w, h) in faces:
        # 实际项目中应使用更精确的关键点检测
        landmarks.append({
            'face': (x, y, w, h),
            'eyes': [(x + w//3, y + h//3), (x + 2*w//3, y + h//3)],
            'mouth': (x + w//2, y + 2*h//3)
        })
    
    return landmarks

2. 智能美颜算法

def apply_beauty_filter(image, strength=0.5):
    """应用智能美颜滤镜"""
    # 1. 皮肤平滑
    smoothed = cv2.bilateralFilter(image, 9, 75, 75)
    
    # 2. 锐化细节
    kernel = np.array([[-1, -1, -1], 
                       [-1, 9, -1], 
                       [-1, -1, -1]])
    sharpened = cv2.filter2D(image, -1, kernel)
    
    # 3. 混合结果
    result = cv2.addWeighted(smoothed, 1 - strength, sharpened, strength, 0)
    
    # 4. 调整亮度对比度
    result = cv2.convertScaleAbs(result, alpha=1.1, beta=10)
    
    return result

3. 牙齿美白与眼睛增强

def enhance_features(image, landmarks):
    """增强面部特征"""
    # 牙齿美白
    for face in landmarks:
        x, y, w, h = face['face']
        mouth_x, mouth_y = face['mouth']
        
        # 牙齿区域
        teeth_roi = image[mouth_y-10:mouth_y+20, mouth_x-30:mouth_x+30]
        
        # 美白处理
        teeth_roi = cv2.cvtColor(teeth_roi, cv2.COLOR_BGR2HSV)
        teeth_roi[:, :, 1] = teeth_roi[:, :, 1] * 0.7  # 降低饱和度
        teeth_roi[:, :, 2] = np.clip(teeth_roi[:, :, 2] * 1.3, 0, 255)  # 增加亮度
        teeth_roi = cv2.cvtColor(teeth_roi, cv2.COLOR_HSV2BGR)
        
        # 应用回原图
        image[mouth_y-10:mouth_y+20, mouth_x-30:mouth_x+30] = teeth_roi
    
    # 眼睛增强
    for face in landmarks:
        for eye in face['eyes']:
            eye_x, eye_y = eye
            
            # 眼睛区域
            eye_roi = image[eye_y-15:eye_y+15, eye_x-15:eye_x+15]
            
            # 增强对比度
            eye_roi = cv2.convertScaleAbs(eye_roi, alpha=1.2, beta=10)
            
            # 应用回原图
            image[eye_y-15:eye_y+15, eye_x-15:eye_x+15] = eye_roi
    
    return image

六、工业级优化方案

1. 多线程处理

from PyQt5.QtCore import QThread, pyqtSignal

class ProcessingThread(QThread):
    finished = pyqtSignal(np.ndarray)
    progress = pyqtSignal(int)
    
    def __init__(self, image, operation):
        super().__init__()
        self.image = image
        self.operation = operation
        
    def run(self):
        result = None
        if self.operation == 'remove_bg':
            result = self.remove_background(self.image)
        elif self.operation == 'change_bg':
            result = self.change_background(self.image)
        
        self.finished.emit(result)
    
    def remove_background(self, image):
        # 模拟耗时操作
        for i in range(1, 101):
            self.progress.emit(i)
            self.msleep(50)
        
        # 实际处理
        return ai_background_removal(image)
    
    def change_background(self, image):
        # 类似实现
        pass

2. GPU加速

def enable_gpu_acceleration():
    """启用GPU加速"""
    # 检查CUDA支持
    if cv2.cuda.getCudaEnabledDeviceCount() > 0:
        # 设置OpenCV使用CUDA
        cv2.cuda.setDevice(0)
        
        # 加载模型到GPU
        net = cv2.dnn.readNetFromONNX('model.onnx')
        net.setPreferableBackend(cv2.dnn.DNN_BACKEND_CUDA)
        net.setPreferableTarget(cv2.dnn.DNN_TARGET_CUDA)
        
        return net
    else:
        # 使用CPU
        return cv2.dnn.readNetFromONNX('model.onnx')

3. 批量处理系统

def batch_process_images(input_dir, output_dir):
    """批量处理证件照"""
    import os
    from concurrent.futures import ThreadPoolExecutor
    
    # 创建输出目录
    os.makedirs(output_dir, exist_ok=True)
    
    # 获取所有图片
    image_files = [f for f in os.listdir(input_dir) if f.lower().endswith(('.jpg', '.png'))]
    
    # 使用线程池并行处理
    with ThreadPoolExecutor(max_workers=4) as executor:
        futures = []
        for file in image_files:
            input_path = os.path.join(input_dir, file)
            output_path = os.path.join(output_dir, file)
            futures.append(executor.submit(process_single_image, input_path, output_path))
        
        # 等待所有任务完成
        for future in futures:
            future.result()

def process_single_image(input_path, output_path):
    """处理单张图片"""
    image = cv2.imread(input_path)
    if image is not None:
        # 应用全流程处理
        image = ai_background_removal(image)
        image = apply_beauty_filter(image)
        image = generate_id_photo(image)
        cv2.imwrite(output_path, image)

九、部署与使用指南

1. 运行说明

1. ​​安装依赖​​：

   pip install opencv-python pyqt5 numpy

2. ​​运行程序​​：

   python photo_editor.py

3. ​​使用流程​​：

   • 点击"加载照片"选择照片
   • 点击"一键抠图"移除背景
   • 点击"更换背景"选择新背景
   • 调整虚化滑块控制背景虚化程度
   • 点击"保存证件照"生成排版证件照

2. 打包为可执行文件

# 安装PyInstaller
pip install pyinstaller

# 打包程序
pyinstaller --onefile --windowed --icon=app.ico photo_editor.py
