由pHash算法识别出的相似图片的GUI代码

以下是使用Python和PyQt5编写的简单GUI代码示例，用于使用pHash算法识别相似图片：

from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QVBoxLayout, QHBoxLayout, QPushButton, QFileDialog
from PyQt5.QtGui import QPixmap
import imagehash
from PIL import Image

class MainWindow(QWidget):
    def __init__(self):
        super().__init__()

        self.setWindowTitle('Image Similarity Checker')

        # 创建组件
        self.label1 = QLabel('Image 1:')
        self.label2 = QLabel('Image 2:')
        self.image1 = QLabel()
        self.image2 = QLabel()
        self.button1 = QPushButton('Upload Image 1')
        self.button2 = QPushButton('Upload Image 2')
        self.compare_button = QPushButton('Compare Images')

        # 创建布局
        self.layout = QVBoxLayout()
        self.layout1 = QHBoxLayout()
        self.layout2 = QHBoxLayout()

        # 添加组件到布局中
        self.layout1.addWidget(self.label1)
        self.layout1.addWidget(self.image1)
        self.layout1.addWidget(self.button1)

        self.layout2.addWidget(self.label2)
        self.layout2.addWidget(self.image2)
        self.layout2.addWidget(self.button2)

        self.layout.addLayout(self.layout1)
        self.layout.addLayout(self.layout2)

        self.layout.addWidget(self.compare_button)

        # 设置主窗口布局
        self.setLayout(self.layout)

        # 连接按钮点击事件
        self.button1.clicked.connect(self.upload_image1)
        self.button2.clicked.connect(self.upload_image2)
        self.compare_button.clicked.connect(self.compare_images)

        self.image1_path = None
        self.image2_path = None

    # 上传图片1
    def upload_image1(self):
        fname = QFileDialog.getOpenFileName(self, 'Open file', './')
        if fname[0]:
            self.image1_path = fname[0]
            pixmap = QPixmap(fname[0])
            self.image1.setPixmap(pixmap)

    # 上传图片2
    def upload_image2(self):
        fname = QFileDialog.getOpenFileName(self, 'Open file', './')
        if fname[0]:
            self.image2_path = fname[0]
            pixmap = QPixmap(fname[0])
            self.image2.setPixmap(pixmap)

    # 比较图片
    def compare_images(self):
        if self.image1_path and self.image2_path:
            hash1 = imagehash.average_hash(Image.open(self.image1_path))
            hash2 = imagehash.average_hash(Image.open(self.image2_path))

            similarity = hash1 - hash2

            if similarity == 0:
                message = 'The images are identical'
            else:
                message = f'The images are {similarity} bits different'

            # 创建messagebox并显示结果
            QMessageBox.information(self, 'Image Similarity', message)

if __name__ == '__main__':
    app = QApplication([])
    window = MainWindow()
    window.show()
    app.exec_()

该程序使用PyQt5创建了一个简单的GUI，有两个上传按钮，用于选择要比较的两个图像，并有一个比较按钮。当用户单击“比较”按钮时，程序将使用pHash算法计算两个图像之间的相似度，并在消息框中显示相似度。
