修改代码：image_paths = ['E:/keti1/2023/xiangjibiaoding/image/1.jpg']为读取文件夹中全部照片

可以使用Python的os模块和glob模块来实现读取文件夹中全部照片的操作。修改后的代码如下所示：

import cv2
import os
import glob

# 获取照片文件夹路径
folder_path = 'E:/keti1/2023/xiangjibiaoding/image/'

# 获取照片文件夹中所有照片的文件路径
image_paths = glob.glob(os.path.join(folder_path, '*.jpg'))

# 遍历照片文件路径列表，读取并显示每一张照片
for image_path in image_paths:
    image = cv2.imread(image_path)
    cv2.imshow('image', image)
    cv2.waitKey(0)

cv2.destroyAllWindows()

上述代码中，我们使用`glob.glob()`函数获取了照片文件夹中所有以`.jpg`为后缀的文件路径，然后遍历这个文件路径列表，读取并显示每一张照片。

import os import cv2 import numpy as np from whale_optimization_algorithm import WhaleOptimizationAlgorithm # 定义图像增强函数 def image_enhancement(img): # 在此处添加对图像的增强操作 return img # 定义鲸鱼优化算法的适应度函数 def fitness_function(x): # 在此处添加对图像增强参数的处理和应用 # 返回适应度值 return 0 # 获取文件夹中所有图像的路径 def get_image_paths(folder_path): image_paths = [] for file_name in os.listdir(folder_path): if file_name.endswith('.jpg') or file_name.endswith('.png'): image_paths.append(os.path.join(folder_path, file_name)) return image_paths # 读取图像并进行增强 def enhance_images(image_paths): for image_path in image_paths: # 读取图像 img = cv2.imread(image_path) # 进行图像增强 enhanced_img = image_enhancement(img) # 保存增强后的图像到另一个文件夹中 new_image_path = image_path.replace('original', 'enhanced') cv2.imwrite(new_image_path, enhanced_img) # 使用鲸鱼优化算法对图像进行增强 def enhance_images_with_woa(image_paths): for image_path in image_paths: # 读取图像 img = cv2.imread(image_path) # 定义鲸鱼优化算法参数 woa = WhaleOptimizationAlgorithm(fitness_function, 10, 50, 100, 2, -2, 2) # 进行图像增强 enhanced_img = image_enhancement(img) # 保存增强后的图像到另一个文件夹中 new_image_path = image_path.replace('original', 'enhanced') cv2.imwrite(new_image_path, enhanced_img)在image_enhancement函数中添加适合的函数，在fitness_function中添加合适的函数

根据代码的结构，image_enhancement函数应该是对输入的图像进行增强操作的函数，而fitness_function则是对鲸鱼优化算法的适应度函数，应该是对图像增强参数进行处理和应用的函数。

对于image_enhancement函数，可以根据具体的需求添加一些常见的图像增强操作，例如：

def image_enhancement(img):
    # 转换为灰度图
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
    # 均衡化直方图
    equalized = cv2.equalizeHist(gray)
    # 进行高斯模糊
    blurred = cv2.GaussianBlur(equalized, (5, 5), 0)
    # 边缘增强
    sharpened = cv2.Laplacian(blurred, cv2.CV_8U, ksize=3)
    # 提高对比度
    enhanced = cv2.convertScaleAbs(sharpened, alpha=2, beta=0)
    return enhanced

上述代码中，首先将彩色图像转换为灰度图，然后对灰度图进行直方图均衡化、高斯模糊、边缘增强和对比度增强等操作，最后返回增强后的图像。

对于fitness_function函数，应该根据具体的图像增强操作来确定适应度函数，例如可以计算图像的清晰度和对比度等指标，具体实现可以参考以下代码：

def fitness_function(x):
    # 解码增强参数（假设有两个参数）
    param1, param2 = x
    # 在此处添加对图像增强参数的处理和应用
    # ...
    # 计算图像清晰度和对比度
    sobelx = cv2.Sobel(img, cv2.CV_64F, 1, 0, ksize=3)
    sobely = cv2.Sobel(img, cv2.CV_64F, 0, 1, ksize=3)
    sobel = np.sqrt(np.square(sobelx) + np.square(sobely))
    clarity = np.mean(sobel)
    contrast = np.std(img)
    # 返回适应度值
    return clarity * contrast

上述代码中，首先将输入的增强参数进行解码，然后根据解码后的参数对图像进行增强，最后计算图像的清晰度和对比度指标，并将二者的乘积作为适应度值返回。

修改以下代码使其能够输出模型预测结果： def open_image(self): file_dialog = QFileDialog() file_paths, _ = file_dialog.getOpenFileNames(self, "选择图片", "", "Image Files (*.png *.jpg *.jpeg)") if file_paths: self.display_images(file_paths) def preprocess_images(self, image_paths): data_transform = transforms.Compose([ transforms.CenterCrop(150), transforms.ToTensor(), transforms.Normalize([0.485, 0.456, 0.406], [0.229, 0.224, 0.225]) ]) self.current_image_paths = [] images = [] for image_path in image_paths: image = Image.open(image_path) image = data_transform(image) image = torch.unsqueeze(image, dim=0) images.append(image) self.current_image_paths.append(image_path) return images def predict_images(self): if not self.current_image_paths: return for i, image_path in enumerate(self.current_image_paths): image = self.preprocess_image(image_path) output = self.model(image) predicted_class = self.class_dict[output.argmax().item()] self.result_labels[i].setText(f"Predicted Class: {predicted_class}") self.progress_bar.setValue((i+1)*20) def display_images(self, image_paths): for i, image_path in enumerate(image_paths): image = QImage(image_path) image = image.scaled(300, 300, Qt.KeepAspectRatio) if i == 0: self.image_label_1.setPixmap(QPixmap.fromImage(image)) elif i == 1: self.image_label_2.setPixmap(QPixmap.fromImage(image)) elif i == 2: self.image_label_3.setPixmap(QPixmap.fromImage(image)) elif i == 3: self.image_label_4.setPixmap(QPixmap.fromImage(image)) elif i == 4: self.image_label_5.setPixmap(QPixmap.fromImage(image))

请注意，代码中的 preprocess_images 函数和 predict_images 函数中的 self.preprocess_image(image_path) 需要修改为 self.preprocess_images([image_path])。修改后的代码如下：

def open_image(self):
    file_dialog = QFileDialog()
    file_paths, _ = file_dialog.getOpenFileNames(self, "选择图片", "", "Image Files (*.png *.jpg *.jpeg)")
    if file_paths:
        self.display_images(file_paths)

def preprocess_images(self, image_paths):
    data_transform = transforms.Compose([
        transforms.CenterCrop(150),
        transforms.ToTensor(),
        transforms.Normalize([0.485, 0.456, 0.406], [0.229, 0.224, 0.225])
    ])
    self.current_image_paths = []
    images = []
    for image_path in image_paths:
        image = Image.open(image_path)
        image = data_transform(image)
        image = torch.unsqueeze(image, dim=0)
        images.append(image)
        self.current_image_paths.append(image_path)
    return images

def predict_images(self):
    if not self.current_image_paths:
        return
    for i, image_path in enumerate(self.current_image_paths):
        image = self.preprocess_images([image_path])
        output = self.model(image[0])
        predicted_class = self.class_dict[output.argmax().item()]
        self.result_labels[i].setText(f"Predicted Class: {predicted_class}")
        self.progress_bar.setValue((i+1)*20)

def display_images(self, image_paths):
    for i, image_path in enumerate(image_paths):
        image = QImage(image_path)
        image = image.scaled(300, 300, Qt.KeepAspectRatio)
        if i == 0:
            self.image_label_1.setPixmap(QPixmap.fromImage(image))
        elif i == 1:
            self.image_label_2.setPixmap(QPixmap.fromImage(image))
        elif i == 2:
            self.image_label_3.setPixmap(QPixmap.fromImage(image))
        elif i == 3:
            self.image_label_4.setPixmap(QPixmap.fromImage(image))
        elif i == 4:
            self.image_label_5.setPixmap(QPixmap.fromImage(image))
